… try doing it first.
Many people say “I cannot do it” without even trying, without even doing their homework, without even doing basic research.
They say “I cannot do it” without even knowing what it really takes.
Before you give up, try doing your homework first.
Read up on other people who have done what you’re trying to do. Learn how they have done it.
Also, someone once told me, “Before you ask a question, do your homework first.”
I guess doing your homework not only gives you an extra lift when you’re about to give up. It also helps you answer the question, “How can I do it?"
