Your attitude is everything. Pick a good one.

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

Success is a journey, not a destination.

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

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

You cannot start the next chapter of your life if you keep re-reading the last one.

Practice like you’ve never won. Perform like you’ve never lost.

Failure to prepare = preparing to fail

The wise person knows that no answer is also an answer

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.
