Sounds pretty good so far, Alcea Rosea. Hope things go well on this project.
Anja, you think so? I mean, I guess the praise "energizes" me, but I would've done the work anyway. Wouldn't I?
I don't know you well, Cimarron, but as an ISTJ, I can imagine that you would do the work anyway.
You know I'm only talking about my particular pet ISTJ.

And what works best for us.
There is a pattern he has which I've noticed. He is eager to do the work and takes over nearly any situation where the opportunity is open. If this goes on for too long without recognition of his efforts he "burns out." Then he finally expresses his needs. And it comes out like this: "Why do I do all the work around here and never get any thanks?"
It doesn't occur to him to ask for his emotional needs until they are crashing down on him. This is a set-up for him to become discouraged. He rarely remembers to ask if I need help as well.
Because I know him well I sometimes anticipate his emotional needs and provide a little support as he goes to help him out. I might add, that sometimes I also get tired of doing this without him remembering to ask for it. That irritation works both ways. I might say something like, "Well, why didn't you say you needed some assistance/appreciation?"
But, yes, he would do the work anyway. He truly is a good and helpful person. And then he possibly could begin to feel resentful.
He's an INFP's dream I admit.

And I need to be careful that I don't take advantage of his generosity with his time. It's easy to take him for granted because of his devotion to duty.
I might also add, that sometimes it's irritating to have him jumping into my projects almost on automatic pilot without checking with me first to see if I actually want or need help! The balance thing.
I remember to verbalize these possible potholes ahead of time and he usually only sees what needs to be done and does it. I'll hear something like, "Stop talking and let's git 'er done." Heh.
Human interaction isn't much valued by him until he bumps into it.
When we work as a team it's pretty awesome. When we don't, it's an argument in the making.
