As a developer, is it just a common experience to find yourself with so much wasted time and effort?

I’m talking about genuinely pure wasted time and effort. Zero beneficial gain, no lesson, no reward, or productive outcome. No “everything happens for a reason” Just flat out plain senseless wasted time and effort, you can never get back or make something out of.

I find myself with a lot of this in this field, and I’m going nuts carrying the burden that just keeps stacking over time. I feel like there’s so much room to make these mistakes, and find yourself in these situations.

Yes a lot of the time you can extract positives out of it, but other times I find it practically impossible to.
Do others feel this way? How do you deal with it?!
