Future focus

I want to believe from my future. I want to be able to envision endless possibilities and be able to create so much more. Contribute so much more. But I know my eyes are still set on the past, almost without fully realizing it. On what I’ve already done. Am able to do. On the “shoulds”, “shouldn’ts” and other status quo. The possibilities within that gaze don’t feel endless at all. They feel tired, worn, and lacking. No one in my family has ever done anything as big as I am thinking. So I think I get scared and back off? But I want more. So when I’m not feeling defeated, I feel a bit of this struggle or battle.

Where should I start?
