I need to develop my Se badly as well.
I am REALLY bad at understanding external details, such as body language etc.
Someone once said that I am more of the "stop and smell the roses" type of guy. I thought to myself, "that isn't me at all!" I am constantly lost in my own head. I often find that I need to slow down and enjoy more things in life, yet I also find that I don't like to do it.
I am so good at contradicting myself...
Do you have instances when you're forced to step up and use your Se? I find that my Se works best when I'm on an adrenaline rush or really pressured. It's not a very strong Se, but its pushed to the forefront in times of crisis.
Thing is, I can't ever recall my state of mind when I'm in this mode. All I know is that I'm very task-oriented and I'm instantly and instinctively collecting the information I need to get shit done.
I wonder if hyper-focus falls under the Se category? In which case, I'm pretty much screwed. I can't control mine.
