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. 

Never underestimate the importance of small steps. small steps = big changes. 

Procrastination makes easy things hard and hard things harder.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

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

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

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 journey of a thousand miles begins with one step. 

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

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.

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

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Your limitation - its only your imagination.
