Keep trying. It's only from the valley that the mountain seems high.
Is your fear of failure greater than your desire to succeed?
Happiness is the result of what you do.
Put all excuses aside and remember this: YOU are capable.
When obstacles arise, you change your direction to reach your goal; you do not change your decision to get there.
The only way to reach the mountain peaks of life is to forget about self and help other people reach greater heights.
