''Nothing in life ... even a few broken bones, is without its reward.''- John le Carrie, writer

Work is hard, but it has its reward. Doing what you have not done before is scary, but it has its reward. 
It does not matter what you are doing, where you are doing it, do not get discouraged. Do not let the toughness discourage you. 
Focus on the reward,  not the pain. 
Focus on what you are becoming, not on what you are going through.
When it comes to success, nothing is without its reward.
