If you are always not interested with your work, you will never grow, you will never learn. As long as a man stands in his own way, everything seems to be in his way. Be creative, resourceful, and inventive. It is not enough that you are doing well in your job, you must do it the right way. If you think you can win, you can win.
Faith is necessary to victory.
Never indulge to pessimism. Negative thinking is oftentimes the main reason for failure. There will always be problems and hardships, but those are the things that make victories sweeter. Take them as challenges and always believe in yourself. Nothing in your work is to be feared.
