I don't agree with what your friend said. Life is about opportunities. Sometimes there opportunities we aren't ready for, then they present themselves again when we are ready...and sometimes even more than that. There are no limits to chances, I don't think the universe operates that way. You know like J.K Rowling approached 12 major publishing companies to sell Harry Potter. Each of those could be called a "chance", right? She didn't stop after 2.
You deserve the best, don't deprive yourself. You ARE worth it.
