I've mentioned a few times about how we all change methods from time to time. If you have ADHD, this will only happen more. I have changed methods for time tracking, time budgeting, and scheduling so many times. When you have ADHD, it is easy to want to change something because you get tired of something. While that can definitely be detrimental in some aspects of our life, there are circumstances when this can work for the better.
You find something that works better. There are many people who just continue to do the same thing over and over again just because they have been doing it. It is not the best way anymore and maybe never was, but just was something they always have done. If you change methods frequently you have a much better chance of finding something that works better.
You won't get stuck in a rut as easily. We all can get stuck in a rut, but it is less likely when we change our methods frequently.
There are more ways to evaluate yourself. The more methods we try and the more we can discover what we are good at and what doesn't work well for you.
You develop a habit of finding the best solution. When you learn to get the negative aspects of this trait under control, you can use this to your advantage.
This should be an encouragement if you find yourself switching from one thing to another too often. This can serve as a reminder that there is a positive way to channel this part of yourself.
