Are we to serve endlessly?

[AnthroHeart]

In order to make it to 4D positive, are we to serve endlessly?
Like serve, serve, and serve more?

I help my mom out, and try to make her happy, but it seems I can't make her happy most of the time.
Does this mean I have failed in serving her?

And when she's moved away, does this mean I will have nobody to serve? Because nobody lives with me.

The only thing I'd think of I'd want to serve is an animal shelter, but I can't stand being bitten by a dog or a cat.
It would make me angry and would do more harm than good.

I've given gofundme donations to shamans.

I don't know what else I can do.
