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

The journey of a thousand miles begins with one step. 

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

In order to become better than anybody else you must first become better than yourself.

The greatest enemy to human potential is your comfort zone

Your attitude is everything. Pick a good one.

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

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. 

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

Dreams don't work unless you do.

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

We learn more from failure than we do from success.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

Success is the sum of small repeated efforts, day in and day out.
