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

Instead of finding reasons why you can't, find reasons why you can.

The road to success is like a staircase. If you want to succeed, double your failure rate

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.

I have not failed, I've just found 10,000 ways that won't work.

We all make mistakes. What matters is how we choose to move forwards from them.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

The greatest enemy to human potential is your comfort zone

Dreams don't work unless you do.

Time is your friend, impulse is your enemy.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Success can never happen without the journey (struggle).

If you can understand just one thing thoroughly, then you will understand everything.
