Much important change happens one individual at a time. So I would say: 1) Honesty (with kindness). 2) Treating others the way oneself would want to be treated (the Golden Rule). 3) Be observant for anyone doing anything good & praiseworthy and encourage them ("good job at ___ing! Way to go! I like it!"). 4) find opportunities to serve, and also encourage others. One way is via https://www.justserve.org/ https://www.justserve.org/ which lets individuals find organizations looking for local volunteers, or organizations post what they do so individuals can find them (free). edit: 5?: While at it, be good to your family. An excellent long-term investment.
