It’s true what they say about finding a solution to the problem rather than finding a problem for the solution.
This is what happened to me yesterday during a discussion. I tried to find a problem for an existing solution to solve and ended wrecking my train of thought and losing sight of what I should be trying to solve. I actually got stumped by myself while trying to gather my thoughts. Took me about half a day to recover and reorganise myself.
Phew!
