Success can never happen without the journey (struggle).

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

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

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

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

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

There is no elevator to success, you have to take the stairs.

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.

I think, therefore I am.

Tough times never last, but tough people do.

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

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

I can is 100 times more important than IQ.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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