Too often you do things you shouldn't.
Because you worry that if you don't answer that email at 11pm, if you don't squeeze them in this week, if you don't work within their budget, if you don't do the extra round of revisions for free, if you don't accept their god damn Facebook request, there's going to be a consequence.
But there's a difference between doing what's best for your business.
And doing what's best for your guilty conscience.
