1. You are not saving the world. You are just a runner. Maybe a good one. But still just a runner.
2. The universe does not owe you anything.
3. Get some perspective on your self-importance.
4. If you can't afford a uniform, and the school doesn't or won't provide them, try approaching local business to donate one to you or to provide the funds to buy one. You will be surprised how many will step up. But ask humbly. Not like a whiny bleating sheep.
