Just push through it all, don’t let anything stand in your way. If you want something then fucking go and get it. Don’t wait for it to be handed to you, you have to go and get something. Life isn’t full of hands out, it is a world full of people trying to take what you have to get to where they want, never let happen.
Work harder than them, achieve more than them, be fiercer than them, be happier than them and don’t hold it against them. Shake their hand after the war has been won and be grateful for such firce competition, it is these people that have pushed you to where you are now.
