The master has failed more times than the beginner has even tried

You can have results or excuses, not both

I think, therefore I am.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

The greatest mistake we make is living in constant fear that we will make one.

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

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

Just stick with it, what seems hard now will one day be your warm up.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

There are no shortcuts to any place worth going.

There is no elevator to success, you have to take the stairs.

The journey of a thousand miles begins with one step.

Procrastination makes easy things hard and hard things harder.

Tough times never last, but tough people do.

The bad news is time flies, the good new is that you're the pilot.
