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

The temptation to quit will be the greatest when you are about to succeed

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

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

The road to success is like a staircase. If you want to succeed, double your failure rate

Knowledge is of no value unless you put it into practice.

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

FAIL - First Attempt In Learning

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

I think, therefore I am.

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

We learn more from failure than we do from success.

Everything you want is on the other side of fear

Tomorrow is worth more than yesterday but less than today.
