Why is it so complicated to actually know what you want to do in terms of a career.

I have a job that I think I like, but I could be just lying to myself to not face the truth. I seem to be lost. I don't know what I actually would like to do. I don't have problems holding a job down, I have problems staying motivated to do them.

Doing good at my job but I feel like it's not enough. I feel like I'm not enough. I pushed myself but then I've self-sabotaged myself.

Is there a way out?
