FAIL - First Attempt In Learning

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

You can hire a tutor but you can't hire someone to practice for you.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

There are no shortcuts to any place worth going.

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

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.
