Shout
Shout, shout, SHOUT your love for humankind! Do not let it be subtle!
Ah, don't disturb your neighbors. It is best to not make noise. Shout with your deeds.
Every act of kindness, an assertion people deserve better than they were getting, or else you would not move the world that way. To take every opportunity to reshape the world to be kinder, well, that makes some real noise.
STRAIN against your limits, do everything you can, and push and push so it's clear if you could do one bit more, if you had even a scrap more capacity, well, then you'd help even more. For now, your limits are like a leash chaining you to a world of grief, but it is not an over-stubborn master, you will drag it along bit by bit, eager and smiling and constantly pulling.
There is a stillness that comes from doing everything you can. That is your starting line, and the realization of more capacity is your starting pistol, for this is the race every other good deed was training you for. How far and how fast you will go, with all your training well done. I will be cheering for you, oh yes, that appointment I could never miss.
