Quitting isn't an option.
You've got to write your plans and goals down.
Whatever you do aim to be the best at it.
There comes a time when you have to give up on people & just move forward without them because trying to pull them will only slow you down.
You lose nothing from trying. You lose everything from not trying!
Never climb down the ladder to argue with fools.
Be careful, they may take kindness for stupidness.
