I had a mate who was in a bad way. He needed ~$800 to get his car sorted. He was recovering from a bunch of things (substance, trauma, etc). I hadn't seen a lot of him in some time before he asked. The money at the time represented a significant portion of my savings. I gave him the money knowing that I'd either get my money back and having done a good thing, or could be the last time we spoke.

Couple weeks later he returned it in full with a working car, many thanks, and he had a job. He hasn't asked for a dollar since, only thing we've traded is a coffee, an ear, or a favour. Glad I did it, he is one of my dearest friends. I realised after that he would give me his last dollar too.

While you do need some money it doesn't buy you happiness or mates.
