Life is too short to wake up with regrets. So love the people who treat you right, forget about the ones who don’t, and believe that everything happens for a reason. If you get a chance, take it. If it changes your life, let it. Nobody said life would be easy, they just promised it would be worth it.
Be prepared: When you are 90% done any large project (a house, a film, an event, an app) the rest of the myriad details will take a second 90% to complete.
