Vent: I poured my 100th slab last month and it felt like nothing

I hit 100 finished slabs last month since I started tracking my pours back in 2019. Sounds like a big deal but I sat in my truck after the last one and felt nothing. Half of those pours got torn out within a year because the subbase was junk, or the homeowner wanted it redone, or a contractor cut corners on me. So what does the 100 even mean, right? My brother says every pour teaches you something even if it gets busted out later. But I am starting to think the number is just a number and I should track square footage instead, or maybe how many slabs are still standing after 3 years. We have guys in this trade with 500 pours who still screw up the finish on a hot day. Do you count your pours, your yards, or just keep it in your head?
