keep going.
You won't get anything if you quit will you?
It's not about how many wells you do, it's about what the next well might drop and how cool it could be

There's always going to be a chance (yes pretty small as you've found) that you could get some really nice items. Welling is a great way to find them.
It's no good to just give up due to past failures, you don't get anywhere in life for that, same with slashing, keep going and it'll pay off
