110% is a myth.

No matter how hard you believe in what you are capable of, you can never do more than 100%

Lots of people believe if they aren't giving at least 110% then they may as well not try because they aren't going to make it.

From my experience and even with not being allowed in my maths class, I know that if you achieve 1% effort towards your goal every day by day 100 you will have succeed.

Choose to do your best, this way no matter how you fair out you will always be proud, you will never set unrealistic goals and you will always learn a little or a lot about yourself.
