The problem is (repeat after me) that your computer is seriously messed up, and may work right sometimes but will continue to futz up unpredictably until the slate is wiped clean. If I may suggest a graphic illustration: Your computer is a shooting victim with ten bullet holes, a broken arm and leg, lying in a pool of its own blood. Things are not normal, even if it keeps breathing underneath its electronic veneer. Your computer was basically eviscerated with piles of programs being gutted [while it was unprotected by antivirus software]. Do you understand now?
You are a computer layperson in a technical field. This is why people ask others for advice -- and it matters that who you ask needs to know the right answer too. Such is life...
I am not slowing down to [some people's] speed, ever. I have slowed down to about three-fourths the speed I used to be at! I think I have always maintained the proper priorities and balance. Some people just accomplish more than others is all. It comes from having a higher energy quotient (EQ?).
You need to find things that make you happy beyond other persons
. If you were the only person in the garden of Eden -- and you had the benefit of today's consumer products -- what would you do to pass the time and fulfill your curiosity and exercise your imagination? Go through the list of everything there is to do and decide what you'd like to try: chess, needlepoint, painting and so on. Remember, you are and will become the person you (truly) want to be.
