Just because I can do something, doesn't mean I have the time to do it. There's a difference.

feel this to the very core of my being

Or that it’s something you want to do

Can you instead give the person pointers about how to do it themselves? Or document your workflow as you go and point others to the documentation?

I try to do this as much as possible. Help others to help themselves. Once I've done something once, I don't want to do it again. I have new things to focus on which I haven't done before.
