It is absolutely wise, even if others deem it as unintelligent or unnecessary. But then again, pragmatic intelligence (pragmatism) and wisdom are two totally different things, imo. The world is in constant need of more selfless kindness, as selfless as human acts can be anyway (not being pessimistic, just acknowledging every human is inherently selfish to a certain degree).
As someone who is hitchhiking more and more, it is an absolute gift and - often - a delight. I’ve donated to some charities even though I’m usually very stingy with money.
Unfortunately, due to the social stigma (and uncertainty as to where the money actually goes) that surrounds it, I sometimes hesitate to help homeless people, I can literally feel the stares of other people who think it is below them on my back when I do - both the stares and not helping make me feel bad, though the latter definitely does more so.
I recently watched a documentary about a train station which regularly helps the homeless and I remember thinking, “I wish I had their way of thinking”, as in, I wish I wouldn’t hesitate and care about being judged or interacting with somebody who has been marred by such pain (it is scary, to be honest, and I am scared of feeling their immense pain with them).
So many people are suffering and are threatened by death, and here most of us are bothered by first-world problems (I don’t mean depression - mental health is ALWAYS valid regardless how much money you have - etc.), thinking they got themselves into that mess and should therefore get themselves out without our help - no, that would be too demanding, how dare they.
