Quest of a Rational Dreamer

I am a dreamer …

I dreamt of being a cashier,
Then I realized it was too childish. 
I dreamt of being a teacher, 
Then I realized it needs patience which isn’t my power.
I dreamt of being a chef,
Then I realized I can be one even without getting the degree.
I dreamt of being a director, 
Then I realized others are more worthy.
I dreamt of being an environmentalist, 
Then I realized everyone should do their duty,
Being an environmentalist isn’t a profession but an advocacy.

So now I’m stocked in this pit of dreams buried by realizations,
If dreams are one’s escape to reality,
Then why do realizations still bother me?
