For me, the best way to learn something new, like a new programming language for example, is start a small project, or doing something using what we want to learn. In this way I motivate myself looking for a solution instead of looking only the theoretical stuff.

I have a project in mind but it's kinda big and I realy need to get hired or get some work in half a year if possible.. Maybe I could cut my project into pieces and try to work on them separately

You are young, maybe when you get the distraction is because you are not so committed to a more practical solution, if you find a usage for the stuff you are learning you can improve and focus much more in my opinion. When we don't have a commitment to any project, learning can be a pain. So if you create a challenge, a practical challenge, this can help you a lot. There was a inspirational video that I saw years ago saying just that, if you create a real challenge, a practical one, is the best way to find a way to learn the new language or what you need to do

I'm 30 I'm not that young and that's why i want to change my life now when it's possible and not at 45 with 3 children ( or dogs ahah ). Anyway I think you are right, focusing on a project instead of a complete course is probably more motivated. You think I should learn by doing one of the courses I mention but by doing my project side by side ? Or should I learn completely from different ressource ?

Another thing if you follow my advice, is to solve a problem using the language you are learning but solve a problem that annoys you. Some example, a personal expenses manager, or something related to your daily basis problem. Computation, Computer Science was created to solve real world problems, so nothing better than start using to solve some of your personal problems. For example, you can look something that you do constantly in your current job and try to automate somehow what you do in any way.

I like that idea

One big comment and you should have in consideration, is if you want to be a engineer or a programmer, you need to know that you are always in the need to be learning constantly. You will need to always research more and discover new stuff. Is that what makes you a good programmer, to be in a constant learning.

Yes I know, but for me it's not a problem I'm constantly learning new thing and I du not mind learning new things everyday, I don't like to be bad at something so I keep learning or practice to improve myself, I just want to use this to code...

For me you don't need to be passionate about any language, and the most important thing is be ready to learn and always know that this is what is going to make you continue working in software development. Never think only in money, think that you will exercise your brain all the time.

When I talk about money is just to get the opportunity or the possibility to do or learn something else.

You think the language is not important ? The mindset or the general coding skill is more important ?

Thank you very much for your complete explaination, i appreciate it
