This all may sound cliche and not as luxurious as much as flexing your ego and showing off can, but whether now or when you get older, you'll come to value the point of de-centering your ego if you want to progress in life, generally and personally.
I'm quite the opposite actually, I am constantly rambling about my interests and this year I even explicitly said what items I would love to receive for my birthday about two weeks in advance.
Maybe this would be easier if I felt like I was ugly, or off putting, or stupid, or a bad flirt, or just a bad person who uses women because I don’t care.
