The hard work, the problems you can’t solve, don’t get easier, they get familiar.
We get better at solving them because we are familiar with all the constraints, context, and, constructs that surround them.
Change any one of those components and the problem didn’t become harder again, it became unfamiliar.
Step away from working on that problem for a few months and then go back to it, the problem itself isn’t harder, you’ve simply lost your familiarity with it.
Your familiarity with problems is what makes them easier, nothing else changed.
