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. 

Time is your friend, impulse is your enemy.

Everything you want is on the other side of fear

It doesn’t matter where you start, it matters how you end

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

Skills are built not born.

Dreams don't work unless you do.

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

In order to become better than anybody else you must first become better than yourself.

Tomorrow is worth more than yesterday but less than today.

It is never too late to turn an unproductive day into a productive one.

Success can never happen without the journey (struggle).

Go as far as you can see, when you get there, you’ll be able to see further

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

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