Sadness and Regrets

I just wanna share to you guys that I can't open my file on my new device. My heart broke. I wasn't that far, around winter of the 1st year, but still, sigh. But that's okay because I have some regrets that I probably can fix that up in my new file soon. So I wanna ask do you guys have any regrets while playing this game that came up from yourselves?

Mine was losing the rusty sword accidentally, not saving things that actually would help for the community center, didn't understand that the meaning of reaching level 5 of mining was actually getting to the 5th floor, which according to the wiki, we should kill 10 slimes to enter the adventurer's guild AFTER getting to the 5th floor, so I tried hard to kill 10+ slimes with scythe and still cannot enter the adventurer's guild (I felt betrayed LMAO), waiting for 3 weeks for the crab pots to catch something without putting bait to it, and lots of things...
