I'm not a soft person. I'm neither delicate nor sentimental. I'm pretty strong willed and assertive. A few different people have said that I come off as very intimidating.
Despite the rough exterior: I really dislike conflict, so I try to avoid it at all costs. I put up with a lot of bullshit and antics with just a wry smile and a silent nod. Maybe that makes me seem nice. Meh.
However, I won't tolerate cruelty, ignorance and/or unfair treatment of myself or others, speaking up in those situations is compulsive for me.
I think the reason INFPs see themselves as having "bad luck" is simply because of our idealistic nature. We tend to see the good side of everyone and when something bad happens, we usually don't want to blame it on bad people. Instead, the blame will be on myself or on the world. Instead of thinking that I got mugged because there is an evil person that needs to be put behind bars, I could think "Oh, it's my fault I walked in that bad neighbourhood" or "I was just unlucky to be in the wrong place, at the wrong time"
Another thing about being idealistic is that the reality will never meet the perfect situations we construct in our heads. And so after something didn't go exactly as we imagined, we will over-analyse and wonder "What if I had done it this way?" or "What if things had gone this way?". So it's pretty easy to say "If I had been luckier, things would have turned out differently"
Personally, I feel I'm luckier than most. I'm terrible at deadlines (dratted P) but things almost always work out in the end. Whether the deadline gets extended, or someone lends a helping hand, or I just get a burst of inspiration. I would rather call it "karma" than "luck" though. Sometimes, being Mr Nice Guy does have its benefits
