Needs have no end.

We all feel that once we have satisfied all our needs, we will feel fulfilled. That's not true. If you keep waiting to finish the bucket list of needs, I assure you you'll kick the bucket sooner than feeling fulfilled.

It doesn’t matter what you want.

Once you get the thing you want, you just want to get something else. Does it mean that it is futile to have desires? No. If you can flow with the flow of the desires, you will never feel less.
