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

You cannot escape the responsibility of tomorrow by evading it today

Shoot for the moon and even if you miss you’ll land among the stars/

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. 

Everything that happens was once a dream.

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

Don't fear failure, fear being in the same exact same place next year as you are now.

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

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

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

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

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

Life is full of opportunities. With every opportunity that is missed, another one is born.

It doesn’t matter where you start, it matters how you end

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.
