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

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

You can be shown the path, but only you can make the first step.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Everything you want is on the other side of fear

Tough times never last, but tough people do.

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

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

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

Failure is not the opposite of success, it is part of the success.

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

You can have results or excuses, not both

The easiest person to deceive is yourself.

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

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