Just Try
Just because you don't know how is no reason to sit on your ass.
Seriously. If you don't try, you'll never know.
Everything ever done had to be tried a first time by somebody.
Besides, your life won't be grand until you have a long list of "Remember when we first did ______?"
And then you get to laugh about your stupidity because you've earned it. Laughing at yourself is way more fun than being afraid someone else will laugh at you.
The early days of CrossFit were full of bunches of us repeating this pattern:
"Uh, you want to try this?"
(Followed by epic failure.)
"Want to go again?"
We tried, we learned, we got better.
Like Greg Glassman says: "The real risk of functional movement is not that you learn it improperly, but that you never learn it at all. The greatest risk is not learning these movements at all."
So, please, make sure you do shit that might seem crazy to you. And do it (sometimes) simply because you have no experience.
I didn't know how to ride a motorcycle when I was 23, so I bought one and learned how.
Ditto on a stick-shift car.
Ditto on Olympic lifting, mountain biking, swimming in triathlons, and kegger handstands.
Feeling alive (and scared) is way more fun than doing nothing because you're scared.
Just jump in. Be smart. Things will be okay. In fact, they'll probably be fantastic.
