“I think that there is only one way to science – or to philosophy, for that matter: to meet a problem, to see its beauty and fall in love with it; to get married to it and to live with it happily, till death do ye part – unless you should meet another and even more fascinating problem or unless, indeed, you should obtain a solution. But even if you do obtain a solution, you may then discover, to your delight, the existence of a whole family of enchanting, though perhaps difficult, problem children, for whose welfare you may work, with a purpose, to the end of your days.”
— Karl Popper
This contrasts with the conventional wisdom that says we do all these tests in science in order to get to the Solution, which we may then be happy with.
In real life, being in a state of no problems isn’t fun — it’s boring. If you have no problems, you’re not working towards anything; you’re not growing; you’re not creating anything. All creative acts involve some kind of problem-solving.
The real thing we should be excited about when we solve problems isn’t the fact they’re over and done with and now we can relax without them — it’s the discovery of new, better and more interesting problems.
