Ahh! There's a name for it then! I call it my backed-against-a-wall syndrom! It is not a comfortable place to be, but it had been the fuel to my most productive moments and self-growth periods over and over. I have learned to welcome it comes.
In those moments, I'm usually open to anything that could potentially, maybe, one day help me. I'm able to make quick decisions, stop thinking and start acting.
Now, if only I could find a way to turn that "switch" on on command, that would be wonderful.
