The one you’ve been waiting for your whole life. First off, you have to believe. You have to belive it it even possible. You also have to realise that there are things, habits or people in your life that are pulling you down. You have no obligation to these. They are moving you in the wrong direction. They have to be eliminated from your life.
You have to stop looking into the past or the future. There is no past and there has never existed a future. These are just useful concepts to use in speech. They have little use in reality. Worrying or regret are productivity's two greatest enemies. They will not add a single productive hour to your life.
You have to do the things you love to do. The things that are moving you in the direction you want to go.
