We all have two lives. The second begins when we realise we only have one. 

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

You can have results or excuses, not both

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

Tomorrow is worth more than yesterday but less than today.

The easiest person to deceive is yourself.

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

It doesn’t matter where you start, it matters how you end

Everything you want is on the other side of fear

If you want to succeed, double your failure rate.

Start, struggle, fail, fix and learn. Repeat.

Procrastination makes easy things hard and hard things harder.

Run in the morning before your body figures out what you're doing

Tough times never last, but tough people do.

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