One realization which has greatly improved my life is this:
The thing that scares you the most is probably the thing you most have to do.
I’m not saying you should dump a bucket of spiders on yourself; but think about what scares you most in life.
For me, this can be something as huge as applying for a job I feel unqualified for, or as small as calling a relative.
Two things happen when you do shit that terrifies you:
1) You realize that you were more scared of the thought of the thing than the thing itself, and
2) You prove to yourself that you can do things you don’t think you can do.
Both of these are incredibly powerful. Stretching your comfort zone is one of the most rewarding and addicting experiences one can…experience (dammit).
The only problem is: It never gets any easier.
So again, I ask: What scares you the most right now?
Go do it.
