Catching on and keeping up

"You need to let go of the control" I hear.
Yet, I am used to having control of what I know and teach. I need to feel confident enough in my own (tech) skills in order to use them to teach my subject (French).
Technology is moving and growing faster every day, so by the time I start using one tool, another one is out there that seem to meet my (students') learning needs better.
How do you keep up?

I have learned so much about technology in the past 3 years, yet I have the constant feeling that I could be learning more.
"Your learning has to change." I hear.

So in joining COETAIL, I am hoping to be learning how to learn.
