ismatu gwendolyn has a great bit of practical advice for unlearning the politics of "deservingness" (ie grappling with giving money to the ppl who "deserve" it most and ultimately not donating anything). they say to train yourself through repetition. set urself a nominal amount every day (even if its just a dollar) and donate to the first mutual aid/donation/gofundme/whatever you see. then thats your social media done for the day.
ive set myself a daily limit of 5 dollars each day. some days i donate 1 dollar to 5 requests, some days i donate 5 dollars to 1 request bc of currency conversion. and ive noticed that often, when i am in the rhythm of donating and ive gotten over the (often shitty, unfounded) mental hurdle of someone else will do it/i cant spare anything right now/a dollar isnt going to help, i donate much more over my personal cap.
like anything, if u want to get better at showing up for fundraisers and mutual aid u gotta practice it. like anything, if everyone mutually decides to care a little bit more and go out of their way for 5 minutes of their day to make a tiny donation, that cumulative community effort really adds up. and like anything, you would want ppl to help you out and give generously if it were you asking for aid.
one dollar a day. just for a week. give it an earnest, real try and i promise u will be surprised at how easy it can be to start showing up.
