Emotions is what we see everyday in our lives, your post is really amazing and insteresting truly.
Whenever I'm angry I tend to destroy things most of the times or just shut everyone and everything out, I just want to be on my own at this point. I don't want to do anything, I don't want to go out and this some times makes me lose alot of opportunities I would have gotten at the time I was at this state, so yes emotions could hinder someone from achieving their dreams.
Best regards dear
Have a great day
