The one thing about change is that it doesn't change.
It just keeps changing.
The world does change... some things don't.
But one thing's for sure. If what you did before doesn't work anymore (in trading or anything), it probably won't magically start working again.
Sticking your head in the sand about it won't fix the problem.
Hoping. Wishing. Whining. Weeping. Groaning. Ignoring. Denying.
None of those will CHANGE things back to the way they were. That’s a definite going forward.
Adapt to the change... or DIE (either a slow lingering death or a fast and ugly one).
Pull your head out of the sand... adapt to change. Embrace it.
Find your groove... and work the hell out of it until you're forced to change again.
That's how the world works, and the Internet makes that change happen even faster.
... and that will probably NEVER change. ;-)
