Dreams don't work unless you do.

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.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

You can have results or excuses, not both

99% of failures come from people who have the habit of making excuses.

I think, therefore I am.

Life is full of opportunities. With every opportunity that is missed, another one is born.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

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).

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Tomorrow is worth more than yesterday but less than today.

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