The "arrogance" you speak of is confidence. I have suffered with major anxiety for the longest time. (most of my life) & now I have my own family calling me crazy sometimes.
I've changed my mindset, set goals & I'm going for what I want in life. I am following my desires & I need to be extremely confident, or I would fail.
I had to get a little crazy. I've sacrificed enough. Now I'm taking what is mine.
