I am completely new.

The courses on the tracks are brilliant, but I have found that I have to stop after each one and do something with the knowledge I have gained by developing my own websites and applications. going through the videos is easy, it's remembering it all that is tough if I don't practise it.

In short, I suggest you do both. I know you said you didn't have time, but just do half as much of each.

As to which language, it depends what you want to do with the knowledge. They are all much the same in terms of logic. It is just the syntax which changes. I suggest you choose a broad one like JavaScript and learn the concepts well. Then it is relatively easy to switch languages and brush up on syntax rules.

The main thing is that you carry on enjoying it!

good luck with your decision

So, I was completely new about 6 months ago. I really wanted out of my career and felt really overwhelmed in trying to make a path for myself. I remember thinking a lot of the things you are thinking. I was obsessed with picking the absolute 'right' steps to get to the 'right place' as fast as possible. Along the way, I fell in love with coding and I code every single day. Every day I try to learn something new. All of the feedback I have gotten about becoming a coder is that that is what coders do- they constantly learn new things. Just keep going, don't be afraid to try new things. Try the different Treehouse tracks out. Try to finish the tracks, try to build stuff on your own. There are tons of online communities and meetups and ways to connect with other people going through the same things as you are. Just do something every day. Your path will become clearer the more you explore and learn.
