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. 

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

No one starts out on top. You have to work your way up.

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

You can have results or excuses, not both

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

We learn more from failure than we do from success.

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

Success can never happen without the journey (struggle).

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

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

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

Procrastination is the thief of time and the enemy of success.
