How Saying No Changed My Life and How It Can Change Yours Too

I used to pride myself in being a "yes girl". If my girlfriends invited me out for drinks, I said hell yeah even though what I really wanted to do was just spend the night reading in bed. If my boss asked if I could take on an extra assignment, I happily accepted even though I was already feeling overwhelmed. "Yes" was pretty much my automatic response to (almost) everything. That need to say yes stemmed partly from FOMO (fear of missing out) and partly from not wanting to let people down.
