Looking at everything around me

I am always looking at things around me, seeing what I can change, where I could go, the things I could do, but all these choices are so many!
I want to travel, have a big family, be successful in my career and so on. But all the time it feels like something always stops me, something gets in the road or holds me back and I can never get a grip again. I can never grab hope for what I want in the future.
