I think, therefore I am.

Failure to prepare = preparing to fail

There are no shortcuts to any place worth going.

Dreams don't work unless you do.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Hard work - a two way street where you get exactly what you put in.

Procrastination is the thief of time and the enemy of success.

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

There are no bad mistakes in maths, only discoveries.

Everything you want is on the other side of fear

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

Our fixed mindset builds our cage, fear keeps us in it.

Tough times never last, but tough people do.

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