Humility is a virtue; timidity is an illness.
Never begin the day until it is finished on paper.
Start from wherever you are and with whatever you've got.
Character is the result of hundreds and hundreds of choices you make that gradually turn who you are, at any given moment, into who you want to be.
Only human beings can reorder their lives any day they choose by refining their philosophy.
The more obstacles you face and overcome, the more times you falter and get back on track, the more difficulties you struggle with and conquer, the more resiliency you will naturally develop. There is nothing that can hold you back, if you are resilient.
