We are in the beginning of another year and it’s time to tướng plan the new year ahead. I think it’s a very good time to tướng share the methodology that I use when I decide to tướng learn any new technology or computer language by myself. It’s very simple and effective. I cannot guarantee that it will be quick or effortless, but it’s very helpful to tướng guide your study, planning and to tướng follow your progress.

The Start
First of all, I choose a book or any other guide for the desired subject and follow all examples and exercises. Without exceptions. It’s very important to tướng follow the “no exceptions” golden rule. It’s good to tướng measure your progress and help you define goals and sprints to tướng follow the plan.
Then, I applied the “Five Rules” method and it will define my behavior for the rest of my trip. Lets go to tướng the rules:
Rule #1: “Wax on wax off”
Write. Do not copy. Never copy. Never.
Do you remember Karate Kid movie from 1984? The story is very similar of 2010’s version. Cobra Kai academy pupils spank Daniel san. Mr. Myagi try to tướng talk to tướng Cobra Kai master in defense of Daniel. Willing to tướng bring peace to tướng Daniel, Mr. Myagi challenge Cobra Kai for a Karate tournament. If Daniel san win, nobody should mess up with him any more. Otherwise his live will become a hell. As Daniel does not know Karate and Mr. Myagi decides train him.
During the training sessions, master Myagi order Daniel execute several strange tasks for a formal training in Karate, lượt thích paint the fence or wax a bunch of cars. Check out the very classical scene where Daniel argue with his master why he needs to tướng tự such task:
My point is, what ever you need to tướng replicate, transcript. Do not just copy & past. Transcription the example or exercise looks lượt thích you are just painting the fence for không tính phí, but you are becoming familiar with new tool and technology. If you just copy & paste you will loose the opportunity to tướng feel some syntax details. Why that comma is there? Open close parenthesis, namespaces correctly placed etc. are such thing is not easily learned when you copy & paste the code. Remember: “wax on wax off”. Transcript, not copy & paste.
Rule #2: Always Use “The Three Steps”
Never move to tướng another example or exercise without execute it without error. Even you spend some hours or days!
I usually tell follow story to tướng my students:
When I was studying for the college acceptance exams, several times I spent hours to tướng solve two or three very difficult mathematic problems. It didn’t make sense for some people, because they think it was a kind of wast of time. However, during those time solving the problem, I dove very deep in the problem trying many ways to tướng solve it. I learnt a lot. By the way, I still remember some solutions, even after đôi mươi years!
In case you are trying some example, tự not copy, write it (Rule #1). After you transcript it, you may tự some typos that you need to tướng correct. It’s a great opportunity to tướng learn troubleshooting and debugging tools.
I always feel the temptation to tướng just copy the code from the trang web and go to tướng the next exercise. When it happens, remember that you are not solving some production issue. You are learning and it takes time.
Besides that, nothing better kêu ca the taste of victory after solve something by yourself.
What about the “Three Steps”?. It’s the problem solving method from my high school teacher:
Follow those steps when you face a very difficult problem:

- Step 1: Cry.
- Step 2: Dry your tears.
- Step 3: Solve the problem.
Rule #3: RTFM (Read the F****** Manual)
Open the API/documentation for each new class/command/control/etc. Understand in detail why the author use it in that example or solution.
You could say that it’s obvious, but it’s not. We tend to tướng accept the solution presented without think too much about that. Check and try new possibilities beyond the author’s solution.
Avoid at any cost the “Stack Overflow Oriented Program”. I didn’t follow that rule when I was learning Objective-C and Cocoa Framework for iPhone programming. I just copy solutions from Stack Overflow and solve the problem. It worked well to tướng solve the issue, but my knowledge remain superficial.
Rule #4: Do Not Rush Your Learning
Try other possibilities not showed by the author.
When I apply the Rule #3, often I see another way to tướng solve the problem beyond the one presented by author. The best thing you could tự for your knowledge is implement and test it.
Again, you are not solving a high priority issue in production, but learning. Enjoy the learning process.
Rule #5: “If you didn’t see, it’s not happened”
Use debugger as much as you can. Only consider the problem finished if you executed all steps through debug tool.
My very first answer to tướng my students during ABAP classes was “did you debugged?”. Not because I don’t want to tướng help, but I want to tướng foster them ví use the debugging tools. It worked. After some time during the class, they only ask my help after several tentative trying to tướng solve by themselves using debug.
During the training class (or self-studying) is the perfect time to tướng learn how to tướng use debug tool, not “on the fly”, in a real situation in front of customer or manager.
When it happens, you train you brain to tướng get used with “on the fly” learning and the nhái feeling that you capable to tướng learn what you need only when need it. There is no incentive to tướng you looking for more deep knowledge. Because that it’s very rare ABAP programmers that have knowledge in debugger tool beyond “/h” and “F’s commands”.
Conclusion
I’m sure you will feel ví good after finish some technical book using my methodology, you will think it’s worth to tướng put it as graduation item at LinkedIn! You will feel that you just accomplish a very difficult mission. It looks hard, but we all know the famous quote “no pain, no gain”.
This text was originally publish my (Portuguese) blog, ABAP101.com. If you are in the begging of your ABAP learning, you could try that methodology in our e-book (in English), ABAP 101 Exercises – Beginner – Starting from scratch. Probably it won’t transform you in a senior ABAP developer, but at least in a junior above the average.
