You should read the power of now by Eckhart Tolle , what he says is that most of our problems in life come from thinking , we either think about the past or worry about the future . He says to stop thinking just stop quit your thoughts , stop tortuting yourself , live in the moment live in the present , do dogs and cats think about the future and past ? No they just eat , poop , mate and sleep . Think of yourself as an ape you are an intelligent ape ( if you are Religious just bear with me here ) , so just live your life , don't let your thoughts give you problems . Whatever happens happens and whatever has happened has happened . Thinking about it does very little other than give you stress. Let go and live in the present now , stop your mind from all the drifting . Practice living for the day and in the moment . Stop and breath and when thoughts enter your mind just say to yourself " stop stop stop , this isn't going to help me or benefit me in anyway stop thinking this stop" . Shut out the voices In your head. I hope this helps as it helps me . Take care and live your life don't THINK your life away .
