You worry a lot, don't you... I've been keeping up with your threads, you speculate about things that may or may not happen in the future, you worry before hand about what may go wrong and speculate about all the why angles as well.
Sounds like a very stressful way to live, I know I'd be much too high strung for my own good if it were me being worried all the time...
Infact, I was super high strung for quite some time, I didn't worry about the type of stuff you do, but I did and do still ensure I have contigency plans for every muck up imaginable.
Except now, I remember to live in the now, and anything present me cannot control is future me's problem. So I let her deal with that shyt while I enjoy myelf.
I hope you can learn to live in the now, embrace it, enjoy it, and make the most of it. Every moment spent worried, is a moment of joy wasted.
