I think many people actually “suffer from this problem,” as they let distractions seep into their daily thoughts. This makes it really hard to enjoy the moment.
A tool I use, that perhaps you find valuable, is asking whether or not an emotion, worry, or thought is in my control at that particular moment.
I try to spend as much time as possible on the very few items that I have control over in that particular space and time.
I find that most of my worries are about things that I have no control over. There is literally nothing I can do to impact any of these things..so why let them come into my present moment and ruin my flow state?
I am religious about spending time on things I care about and not letting stressors take up too much of my precious time.
