 Are you constantly forgetting things that you need to do or tasks that need to get done? Don't worry, you're not alone. Your brain is for coming up with ideas and thinking of those original ideas in the first place, not for storing them and remembering them later on. That's why it's really important that in our day-to-day life we have devices around us where we can take those ideas from our head and put them somewhere else so we can refer to them in the future. Personally, I use a mix of writing things down with a pen and paper and then also using my phone to get reminders and calendar notifications so that I don't forget anything that I need to do.
