I like how I see things in ways that other people don't, and I love the feeling of constantly romanticizing/idealizing situations.
A lot of the things INFJ's tend to have problems with, I actually like. It's true that it's a bit of an emotional roller-coaster ride for me at times, and there're huge emotional burdens that are simply a part of my life. Those things aren't easy to live with, but I wouldn't have things any other way. It all comes with that an INFJ-feeling of purpose.
The only real problem that I have with being an INFJ is how inconsistent my energy level is. Some days I wake up and I feel like laying in bed all day. I can't stand that.
