I hope 2020 will bring you as much joy, peace and low-stress as possible. Without pretending to know all the answers...or ANY answers...in regard to setting your sights on trying new things or setting goals for the year without making those new things or goals "resolutions" but trying to live a better lifestyle, I have some suggestions of which you may have already thought or achieved. Regardless, following are my respectful suggestions:
-Trying new things: The enduring adage, "We never stop learning" I think is applicable here in regard to trying new things that will enhance our lives and lifestyles. At age 82, I'm still learning that what I thought was correct thinking about a multitude of subjects isn't always the case. Thus, when I learn something new. either via media or friends, I immediately acknowledge that information to be an eye-opener that can always make me happy to have learned it. I also apply that new knowledge to trying new thinking about my recreational or non-recreational activities. Even just sitting in one's favorite chair and just thinking about something new can be gratifying, too.
Setting goals for the year - You, more than anyone, know what you want to achieve to reach as carefree a life as possible. Thus, I won't make any suggestions to try to live a better lifestyle.
