"After we had conducted thousands of experiments on a certain project without solving the problem, one of my associates, after we had conducted the crowning experiment and it had proved a failure, expressed discouragement and disgust over our having failed to find out anything. I cheerily assured him that we had learned something. For we had learned for a certainty that the thing couldn't be done that way, and that we would have to try some other way." -- Thomas Edison, the January 1921 issue of American Magazine
It's worth taking up initiatives that might not work, especially if the end result is something that would be worth reaching.
"Let's take a crack at this... it might not work, but let's see what happens..."
If you're trying to break new ground that hasn't been done before, you have to do so knowing that any given way you try to move forward is unlikely to work. You make a rough hypothesis and plan, you give it a shot, and you see if it pays the desired result at a reasonable cost.
It likely won't, but you usually learn something.
This applies, too, when you're chasing down more normal goals. Empirically, most people fail with their first attempts at a fitness regime, at improving sleep quality, at improving efficiency, at reading more, at socializing more, at earning more, at all sorts of things. The second, third, and fourth attempts also often fail as well.
But if you're dead-sure it's worth getting, you keep trying it different ways. You might take the same fundamental approach with a different mindset or slightly different implementation, or you might try something radically different. But you keep trying.
Most people need a sense of certainty that their plans will work, or they won't start. So they'll engage in complete certain but not-so-valuable activities. It lets them feel good, and feel smart, sort of. But embracing the other way -- "hey, this might not work (and likely won't) but I'll definitely learn something" -- is not only more fun, but it seems to lead to a much more enriching life.
Certainty isn't required to try things, and isn't possible for any given way to breaking new ground.
Take a crack at something meaningful. You're only going to succeed, even if it doesn't work.
I call this approach "joyful negativity." I assume most of my efforts will fail and accept that outcome. In truth, most efforts are at least moderately successful, which expands my joy to something higher. The times when I really do something cool or find some other reward are sheer bliss. Set your expectations low, keep your effort on high, and you cannot help but be pleased with the results. That's just my personal philosophy. Sisyphus did it another way . . . .
Personally, I'd add a caveat: Take a crack at something meaningful so long as you don't die ... In other words, if the maximum possible downside is tolerable, and the maximum possible upside is tremendous (this asymmetry qualifies an activity as "meaningful"), then take the leap.
That begs the question: How do you know what the maximum possible downside is? and that's a topic for an entire book ... ('Antifragile' by Nassim Nicholas Taleb)

That site has a lot of great discussions (along with podcasts) on the most recent books.
What's cyclothymia? It's a mild form of the docs used to call "manic-depression," but which they re-name periodically. Cyclothymics can actually function decently well, and as such often don't know they've got it. If you cycle through highs and lows, are particularly artistic, or that describes someone you love, then read this post in full and please comment with your own experience. I'm still learning, myself.
AN INTRODUCTION TO CYCLOTHYMIA
Knowing the term "Cyclothymia" would have been very helpful to me a few years ago. This essay is plain English and, if I've done a good job, might help people who associate with a cyclothymic relate better to them, and might help a cyclothymic manage themselves better and produce better.
I'm against the "medical-ization" of life. We need medical terms, but we need to be able to explain things in plain English without labeling. Labeling, by definition, drastically simplifies.
Cyclothymia is simple at its roots, simple enough for a plain discussion without medicalization. Here's how it works for me -
My life philosophy is "Don't be pseudo."
It can be applied everywhere--school, work, relationships, productivity, and health.
It may not be the key to success (this philosophy tends to rub the masses the wrong way), but it's the only way I can live with myself.
I'm not saying I'm any good at my philosophy. People constantly applaud me for being real, brash, and outspoken, but honestly, I'm still constantly pseudo.
I tell myself that I'll do the work today, or that I'm reading a lot, or that I'll start an exercise habit, or that I've been grooming myself daily, but the truth is, I'm not. I'm still a failure.
