I agree with this:
"Many barriers are in our heads and only in our heads. Don’t let your constraints stop you. Embrace them. You don’t need to be a genius, or own lots of money, or be networked with key people, or be skillful, funny, or good-looking to meet your goals. The ones who were remarkable in life were those who understood their limitations and bent them to their advantage."
I do believe, it is the sustained attempts at overcoming constraints and often overcoming them, that makes a person or company awesome.
