Holy cow you stole words from my brain! But, after battling with this feeling for a while, I've finally come to a working solution.

The mistake I was making was taking other people's results as the lesson. That led me down all the wrong rabbit holes and left me feeling exactly as you do.

What I now do when I listen to Mixergy or any other startup stuff is treat it as stories and try to learn what experiments to run, what to test within the framework of my work.

I do not let any of it derail my own plans.

This means I don't randomly read or listen to stuff any more. When I am working on my site's marketing, I will go and find some marketing material. If I'm working on A/B testing, I'll read up on that.

And finally, sometimes I just have to let go and watch some random stuff because I do enjoy it. It's like war stories to me.

Don't get down. If you're really not getting much work done, then just shut it all out for a bit and get the work done.
