I hate it when I do stupid stuff

Ran plumbing for a new bathroom. Get it all done and find out the shower hot/cold is backwards.. sink is correct. Cut/splice resolder. Shower is fine, sink is backwards. Cut/splice resolder. Sink and shower are backwards. Cut/splice resolder, it's the same again. I ended up reconnecting it the same way as the last one. Fourth time's a charm. Of course, in my cheapness, I had to go to hardware store for couplers three times because I would only buy two at a time lol..
