Life is too short not to live the best version of it you can. That's why you've made the right decision... to commit to a fulfilling life, to become the best version of yourself you can be.
That decision will kick off a series of changes in the way you think and act that will have long-lasting positive impacts on your future self, but at this moment you are in the quiet, anticipatory period between commitment and action.
Take a beat to revel in the moment. Close your eyes, draw a few deep breaths, relax your body. Imagine yourself in one year, five years, twenty years. Imagine that future self thanking your now self for making having the courage to think long term.
