It's true what they say, You'll always know if you're doing the right or wrong thing by how hard it is to do. If it's grueling as hell, then you know you're making the right decision. And even though I can't change my destination overnight I can at least change my direction.
I know life can be hard and there are people who want nothing more than to get what they can out of you. If you have people like that in your life as well, then I understand your struggle. As much as you may love those people in your life, don't let them bring you down.
Sometimes you just have to let them go.
