What makes you spring back to life?

Looking down into the backyard:

This morning I looked down into the garden and was amazed at how green the ground looked. Just a few days ago when we were in the hammock, most of it was hard, brown and dry, from dry season. (See below shot).
The growth is natural, yet miraculous. With just the few days and nights of rain we've been having, the grass is eagerly springing back. The Earth was thirsty for rain and now it is receptive and responsive to each drop being given.

Even looking up to the hills, which often become brown and black (the combination of dryness and burnt out areas from bush & forest fires) ... they regenerate with amazing rapidity every year. From one day to the next the brown becomes a memory.

Something to think about. What makes humans ... us ... me ... you ... spring back like that?
