Everyone pretty much does this. During a moment when you're bored and you suddenly start daydreaming about the glamorous life you'll have in maybe five to ten years is not a problem in my eyes. It's normal to think about the type of life you want in the future. However, if thinking about the future causes you to ignore and miss out on what is happening at the moment then that kind of is a problem. Even though I know that constantly thinking about or worrying about the future is not good, I still seem to do it. It's a habit that is hard for me to break.
I have read many blog posts and watched many videos about how living in the present will make you happier. I've always been the type of person to constantly think about the future; whether it's about something as important as my career or something not as important like which set of pajamas I'm going to wear to bed. I've caught myself multiple times missing out on something due to zoning out and most of the time thinking about something that doesn't matter until later to come. I'll never forget the time I went to see pop and r&b singer, Yuna, perform during my sophomore year of college. I remember I couldn't wait for her to perform my favorite song of hers. When she finally did I unintentionally started thinking about which classes I was going to take in the spring semester! As if that even mattered at the moment! I realized that I was missing the song and brought myself back to earth before it was over.
There have also been many times where I would lose some sleep because I would think about the future, and at times the past as well.
It has never been to the point of me not being able to sleep for so many nights in a row, but I know constantly thinking about the future or past, especially if there is stress added to it, could cause sleepless nights to occur. To me living in the moment is the way to live. Thinking about the future and preparing for it is not at all a bad thing. Even bringing up the past, as long as it is positive or it will be used for teaching is okay too! I believe that it's bad when thinking about the future and past stops you from enjoying what is happening at the moment. I am definitely going to try harder to be more in the present and to enjoy the moment myself.
