This line from an old song by Blind Faith prompted me to say in response----It doesn't matter how much we give of ourselves, all we can do is give what we have. Of course, that's Steve Winwood singing, and he's given quite a lot, in my opinion, and if I had to compare my own giving ability with his, I might feel pretty empty-handed, but that's not the point, is it.
If we value diversity, and if we see that life is not a hierarchy, then what we each give from the overflowing of our beings is enough, plenty, and can only have the wonderful effect of adding to the lovely diversity of life and an increase in all that is good.
No comparisons necessary.
