You say you got bored, but you don't say why. Are you getting bored or is life just getting in the way?

Also the fact that you are concerned about it seems to suggest that it's something "you feel you have to do". Like if you don't do it then you're not acheiving something.

I've been working on a project for years, still get enthusiastic about it, life gets in the way, and I still manage to pick it up where I left off. If this is definitely not you, then Id suggest you are trying too hard.

Stop looking for things to do or be, and just let them happen.

the problem with chasing targets is that there's always someone or something better out there and it can be really depressing when you find out someone else does something with ease (I know I just gave an example) but the point is that by stopping comparing yourself or trying to better yourself because you think that its the done thing, you'll feel a lot better, and the chances are you'll be able to just find things that interest you without trying.
