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

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

The wise person knows that no answer is also an answer

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

Pure mathematics is in its way, the poetry of logical ideas.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Don’t hang your targets after you’re done shooting.

Everything you want is on the other side of fear

Your attitude is everything. Pick a good one.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

You're not in competition with anyone but yourself. Outdo your past, not other people.

Never underestimate the importance of small steps. small steps = big changes.
