I asked for forgiveness of anything I did said or even thought about yesterday that could hinder anything of today ( and the rest of my days) I was forgiven so today is really a new day that shouldn't involve any parts of yesterday's news.
Your are your 'selfish' years. It's a decade to immerse yourself in every single thing possible. Be selfish with your time and all the aspects of you. Tinker with shit, travel, explore, love a lot, love a little and never touch the ground.
