It could be that the purpose of your life is only to serve as a warning to others.
Not every life can be a success, just like not every vessel can be seaworthy. But there’s no shame in being one spectacular shipwreck. (Actually, there is. But we’re not going to kick you while you’re down, Edmund Fitzgerald.)
Instilling the self-confidence kids will need to carry them through all the failure they'll experience because they weren't taught competence instead.
Because there's nothing standing between you and your goal but a total lack of talent and complete failure of will.
