stuck
It's very easy to get stuck.
After traveling a certain direction for a time, your route becomes so narrow or clouded that your ability to push on comes to a halt. You can do one of two things: pull out as far as it talks to readjust to a new route, or mix up your process for doing what got you stuck.
Some ways the latter option has played out for me:
Learning to play tennis left-handed to get past a hump in my game.
Writing at a coffee shop instead of at my house every morning to jog better thinking.
White-boarding a Report question before sitting down to right it up.
Change is the primary component of innovation. Find creativity in your mix-up and you may find the path to get unstuck.
