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. 

Dreams don't work unless you do.

Shoot for the moon and even if you miss you’ll land among the stars/

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

Pure mathematics is in its way, the poetry of logical ideas.

It always seems impossible until it's done.

Hope might be a good breakfast, but it makes a very poor dinner

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Success can never happen without the journey (struggle).

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

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

The easiest person to deceive is yourself.

Procrastination makes easy things hard and hard things harder.

Everything you want is on the other side of fear

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