Is AUTHOR wrong in the post ? POST : So I got a promotion recently and the pay is VERY high. For some background, I am a 26 year old guy and I studied at a prestigious university (top 10 in my country).

Now when I met with my friends to celebrate, we had some drinks and I said ''Deep down, I always knew that I was destined for success'' and one of my friends (26F) said ''Don't be an arrogant arrogant''. 

Wtf, how is that being an asshole? I 100% believe what I said. I had full faith/conviction that I would be a success since I was a kid. I never once doubted or questioned whether I'd be successful. Sure I struggled and had hard times but I always knew I'd be a success, AITA?
