Getting overlooked for a promotion feels awful.
What makes it even worse is when you get passed over in favor of someone who you (and seemingly everyone else knows) is not as capable as you but simply "talks a good game".
The world isn’t fair... but at least you can make it fairer to your advantage by investing the effort and time to improve your public speaking and presentation skills.
Remember, you can be the smartest person in the room, but if you can't express yourself or present yourself in a way that people listen to you - then you will significantly stifle your career prospects.
