Instead of watching another cat video, spend your time online learning something that will help you be more successful. The TED videos are great. Find “Amy Cuddy: Your body language shapes who you are”
She shows how your body language changes your hormone levels and even how that affects how people perceive you. The take-away is that you will be perceived as being more successful, and because of that you will be more successful.
It also brings to mind stage presence and how that will make you a more successful band or performer.
I know someone who was encouraged to take dance lessons. Not that he was going to dance on stage, but it helped him move better on stage. It works!
So, even if you just become more aware of yourself and how your own body language communicates to others, that knowledge can make a huge difference in your success.
That is, if you put it to use.
