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. 

We all have two lives. The second begins when we realise we only have one. 

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

We learn more from failure than we do from success.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Try and do one thing each day that you would really rather not do.

Lose an hour in the morning and you will spend all day looking for it.

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

Success can never happen without the journey (struggle).

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.

Tomorrow is worth more than yesterday but less than today.
