It's better to act than not act, because action brings knowledge: imagine shooting a target in the dark, and can only hear how close you were: <i>Ready. Fire. Aim.</i> (and repeat). It's also literally what you do to find and then correct for a mis-calibrated sight.<p>It's the notion that seeing reality helps <i>a lot</i>. Once you know what is there, you can have ideas that can help. Whereas ideas that are not based on reality are very unlikely to work.<p>minor e.g. I find that my problem solving works best once I've started trying something. With each thing I try, I notice more: similarities, patterns, gaps that could be filled, things that could be connected; and I have ideas about how other things at hand could be used to do that. These are often obvious in hindsight; but I didn't think of them at all beforehand.<p>Of course, one might not succeed anyway - the pop. stat. is 9/10 businesses fail. But not discovering reality has even worse odds.
