I tried sweet potatoes a couple of years ago. Did not work good at all. That was a first and last attempt!
Not having success is a very good reason to try again. Thomas Edison when asked about his 1000 failures to create an electric light said "I have not failed, I have learned 1000 ways not to make an electric light".
He eventually got it right!
