One of my father's favorite sayings was, ‘If a job is worth doing, it is worth doing well.’ In other words, once you have made a commitment, you should apply yourself to it to the best of your ability, not in a shoddy, half-hearted manner.
In my own life, I have discovered another truth: ‘If a job is worth doing, it is worth doing badly.’ In other words, don't avoid doing things worth doing simply because you won't be able to do them very well at first. Be willing and humble enough to start doing something badly and learn from your mistakes. Don't worry about making a fool of yourself. One of the reasons I learnt the Thai language so quickly was that I didn't mind when people laughed at my mistakes.
