A couple of other people have expressed similar sentiments here, and I think it's the truth. You have to be in a position to give before you can sustain it reliably and/or reap the benefits from it.
Often though, this position is highly subjective and mental in nature. A homeless man could willingly give his food away, and still somehow be fine with that, if he believes that things will be fine regardless somehow (perhaps he has an alternative source of food, or sincerely doesn't think that skipping food once will set him back forever). At the other hand, someone with a difficult and tedious job that pays well may not feel like they have the time or energy to give without necessarily receiving anything in return, even though they may objectively be in a much better overall position for it.
I guess altruism necessarily requires some other essential basic needs to be in abundance first before it can overflow.
