Finally, remember that you're in this thing for the long haul. Don't expect to slip up, but be prepared for temporary failure in case it happens. If you do slip up, as soon as you can, get back up and try again. Never for a moment identify yourself with temporary flashes of error. Know that you have been blessed with the power to succeed in your noble resolutions.
Persistence is the mother of success.
Always try once more. You can be anything you want to be, do anything you set out to accomplish if you hold to that desire with singleness of purpose.
