hell is around the corner

I won't be dreaming anymore about my future.
I won't say "I want", "I wish" to anyone.

How come, everyone take so serious someone's words about what he or she want to do for a living in future? i like photography and movies and design etc but it doesn't mean that i'm already as good at this as professionals and people that have been working on it for 10-20 years!
it's so silly and makes me irritated every single time when I'm listening to it.
