You can have results or excuses, not both

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

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

Failure to prepare = preparing to fail

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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

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

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.

Everything that happens was once a dream.

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

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

The wise person knows that no answer is also an answer

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