I saw very much understand you and I'm going to see Steve's new video tonight.
But you know it happened to me many times - I want something deep in my heart, but then circumstances change and I go like "whatever, forget about it, I'll put my attention to this now".. but what I have found out is that I always come back to that deep burning desire becose it keeps reminding of itself. Say I have always wanted to live in a different place and have a more exciting life (and I've lived in a different city when I was younger and I lived in USA and South America for some time, so I got an idea of what it's like to live in a different place). but everytime I come back to this desire and start taking action and get opportunities I seem to hold back by thinking about leaving my family and my "comfort zone", I even feel guilty about it, even though there's no reason for it, so I start looking for things to stay, but the thing is that I ALWAYS come back to this desire and I think it's really time to act now or never..
so what I'm trying to say - try different things and you will FEEL what is it that gives you the most excitement and them move towards it.
but I def understand you as I'm always thinking about many possible paths and can't really concentrate on one specific..
I know, I didn't really help
