Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

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

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

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

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. 

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

If you fail, next time fail better.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

You can be shown the path, but only you can make the first step.

You're not in competition with anyone but yourself. Outdo your past, not other people.

The easiest person to deceive is yourself.

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.

He who has begun his task is half-way done. Have the courage to begin!

Don’t compare yourself to others. Compare yourself to the person you were yesterday.
