If wishes were fishes and cattle were kings, the world would be full of wonderful things
If wishes were instantly granted, we’d all swim in riches
If wishes were horses then beggars would ride,
If turnips were swords I’d have one by my side.
If ‘ifs’ and ‘ands’ were pots and pans
There would be no need for tinker’s hands!
Basically the point is wishes are useless. Or more simply: “Shut up and work harder.” It’s that simple.
