Belief in ourself is like a muscle - it is strengthened by constant and careful use.
If you find a path with no obstacles, it likely leads nowhere.
You can't drive into the future if you are looking into a rear vision mirror.
Pick yourself up when you're feeling down. No one else is likely to.
Dream it. Dare it. Do it.
Focus on what you can do rather than stress about what you have no control over.
