When it's too hard for them, it's just right for us.
Football doesn't build character, it reveals character.
If you believe you are doing a good job in which you enjoy and like, then don't resign regardless of the pressures.
There will be many failures sprinkled among the successes you enjoy.
Expect rejection, but expect even more strongly to overcome it.
A failure becomes just one time at bat if you refuse to let it defeat you.
