you did it, you said it, you wrote it – this is what you thought at the time – it is done – it is over – you can’t change it – don’t overthink it. you don’t know how the other person will perceive it. you meant good. stop analyzing every word. stop going back in your mind over and over. should you change this, should you go back and say this, should you call them, should you re-write what you wrote – just stop. they are busy with their own lives and with their own problems. they actually didn’t think twice about what you said, wrote, did – they are too consumed in their own minds, in their own lives. they are not thinking about you – they are thinking about themselves. they are in their own world with their own things going on. they are walking down the street right now thinking about their life. they are not thinking about you walking down the street. they are not thinking where are you and what are you thinking. they are at the center of their world and you are at the center of your world. so don’t go back and rethink and overthink – don’t go back at all. just say it, write it, do it – and move on because no one is overthinking about what you said, did or wrote – except you. so don’t overthink it because it doesn’t matter.
