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.

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

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

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. 

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Hard work beats talent when talent doesn't work hard.

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

Knowledge is of no value unless you put it into practice.

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

Run in the morning before your body figures out what you're doing

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

The greatest enemy to human potential is your comfort zone

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.
