Don't get me wrong, I worry about things, but I try and remember to work but worry as often as I can and it gets better results.
There's nothing wrong with being concerned about a thing, that's normal, but worrying about it rather than working on it will rarely get shit done.
No I think you are absolutely right on this! That is exactly what I need to learn as well since I still spend too much energy worrying as you said. Not efficient for sure!
