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. 

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

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

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

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

99% of failures come from people who have the habit of making excuses.

Success can never happen without the journey (struggle).

Success is a journey, not a destination.

Procrastination makes easy things hard and hard things harder.

Mistakes have the power to turn you into something better than you were before.

You cannot escape the responsibility of tomorrow by evading it today

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

Do what you have always done and you will always be what you have always been

The journey of a thousand miles begins with one step.

Failure is not the opposite of success, it is part of the success.
