When you spend time trying to imagine things that add no meaning to your life in any way, that means all you are doing is a waste of time and effort. But, your imagination can become productive if it is used in the right way.
This is my greatest problem over the years and I bless Almighty that it has begun to decline in months past.
Focusing on past things without no meaning is a a great disaster
I am happy for you bro, working on our weakness is a good thing to do.
