This article makes so much sense to me, being a past overthinker and a victim of my own depression.
It basically points out that your imagination does not actually enhance your sexuality, it holds it back. I too, have been trying to live in the moment more, it does bring me more happiness by trusting your own smarts and feeling your senses as opposed to overthinking anything that comes up and trying to dissect every detail.
The truth is: we don't know what's going to happen in the future. We really don't. The only thing we can do is live the best you can right this moment (being positive of course!) , and trust what you're doing is pointing you the rightful way.
Hope this helps you come to a realization like it did for me!
