Stoicism revisited

Having a philosophy of living is better than not having one goes the argument. And it doesn't really matter which one you pick. 

It does a few things:

i - Gives you orientation and easier decision making.

ii - Less fear of the end. As much of the fear comes not from simply dying, but realizing at the end that you have not lived well. 

iii - Minimizes the feeling of backtracking. Making progress today only to wander backwards tomorrow.
