Well, I am tired, but generally I think it is worse among INFJs than INTJs, because INFJs tend to be more neurotic. I am just generally bored at the moment, and when I am not passionate about something, I am tired...
Yes, especially now. I just started a new job that requires me to be away from home 10 to 10-1/2 hours on weekdays. The work is interesting, but I have to adjust to new procedures, people, environment, etc.; steep learning curve = fatigue.
My kids are home and my husband snores; when my son's away, my husband can move to another bed, but in the summer that's not an option. So I'm kinda sleep-deprived.
I'm not so busy socially these days, but when I am, that takes a lot out of me, too. These days I come home, eat dinner, do a little email and foruming and watch something entertaining.
And I'm starting school at the end of the month. People my age are retiring and I'm returning to school. You bet I'm tired.
It's normal to be tired though if a person lives a very busy hectic life. People who are patrents of several children and working or people who work full time and go to school as well, will be more tired than others. They are simply using up their energies more than other people, but a fatigue problem is when the energy isn't there to be used to begin with.
I'd be more interested in how tired people are in contrast to how active they are, are you able to call on your energy to meet the daily goals and needs of your life?....but then of course it's not my thread!
