God said:
When you wake up in the morning, ask yourself:
"What can I think of to do today that will bring me even a little joy?"
It's also fine to ask:
"What can I think of to do today that will bring a little joy to the world?"
Basically, the answers to two questions are the same.
Even if what will bring you joy today is a manicure, this is good. You may think a manicure is superficial and couldn't help the world. Just think what the world would be like if everyone who wanted a manicure today got one. Or a massage. Or a sauna. Joy is joy!
It is perfectly fine to find joy where you find it. Start with small-sized bites. No joy is too small. One joy will grow to another.
Let Me backtrack a bit now. If what is joy for you could cause a slight or pain to another, naturally, this does not qualify as a joy for you to take. To take advantage of another in any way, of course, does not qualify. It is not that anything goes.
At the same time, the joy that life today can give you does not have to be on the scale of saving the world. Nor does your joy for today have to be thoroughly magnanimous either. Personal joy is also joy. Start here.
Your joy could be picking a flower. An added joy could be for you to give that flower to someone whose face will light up because you offered a flower. Of course, the joy of lifting someone else's Life is great for you as well.
