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" not them. Be the best version of you.

Success can never happen without the journey (struggle).

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

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.

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

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

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

You can have results or excuses, not both

You cannot escape the responsibility of tomorrow by evading it today

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