I don't know if this restores my sanity, or increases my insanity, but here's what I routinely do to occupy my time as of this moment:

• Work
• Play classical piano
• Read - a lot of James Rollins books currently, adventure/intrigue fiction
• Informal target shooting - previously mostly handgun, but now getting into long range rifle, and expanding from handgun reloading to precision rifle reloading
• Computer - Linux administration, media servers, wasting time surfing the internet, also toying with a Raspberry Pi at the moment (creating my own "NextCloud" server for the family)
• Studying for ham radio license
• Building a portable shooting table
• Going to classical symphony concerts
• Enjoying the hot tub on cold evenings

Unfortunately, I haven't gotten out hiking lately. Or fishing. Now that Spring weather is here/approaching, that will change.
