Nothing is impossible if you want it badly enough. Impossible = I'm possible.

I have not failed, I've just found 10,000 ways that won't work.

99% of genius comes from hard work, the remaining 1% comes from innate talent

99% of failures come from people who have the habit of making excuses.

Dreams don't work unless you do.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Don’t be afraid to work hard and find out how good you can really be.

Success can never happen without the journey (struggle).

Lose an hour in the morning and you will spend all day looking for it.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

You can have results or excuses, not both

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

It is never too late to turn an unproductive day into a productive one.
