Two years ago I wrote myself a letter. Inside of it I told myself to not give up. To not give up on writing, something I believed I was good at, which is rare. Within those years, I stopped believing. I stopped being creative. I made no more time for it. That's when I realize that's how it is to grow up. You just start to lose that spark, that passion. But reading that letter made me reach for a pen and paper.
I really suggest anyone to do this. Writing a letter and trap it in a bottle for a year or more. It'll make you remember good things from the past and maybe some good habits you have lost.
