Anything is possible, if you think it is worthwhile. If you're willing to go the distance, to go the extra mile.
With determination and effort, you can often achieve more because you don't always get what you wish, but what you work for.
Dreams can become challenging, but no matter what the cost strive to complete the task before you, and you'll never end up lost.
So bring with you your goals, and leave your doubts behind. Whether you think you can or can't, you certainly will find you'll be right either way--so never quit, and this is why: You'll never become a failure, until you fail to try.
