be it feeding people, youth outreach, helping people move, the library, community gardens…the possibilities are endless and of course vary. i volunteer for the art program offered by a shelter near me so it’s possible to balance any interests of yours with doing good! take the time to research opportunities that speak to you.
some other helpful ideas: pick a grassroots organization you really resonate with and donate/promote as regularly as you can...read tricky things and have those tricky conversations...learn a domestic or community building skill such as sewing...
best of luck and don’t get too wrapped up in the “size” of the impact of your actions, because a little help is better than none :)
