I fancied a bit of a change so I will relate my experiences in tackling this cliche in the form of a poem.
I thought my giant onion
Would win 'Biggest Vegetable' prize
But some of the other entries
Were four, five or six times the size.
And then at the Marmalade Festival
The judges tried to be kind
But I knew as well as they did
Something was wrong with the rind.
I entered the Japanese Cheese Contest
And was thrilled to finish third
I might have done even better
If I'd been gentler with the curd.
It was at the open mic night
When my poem won the cup!
(Can we keep it our little secret
That nobody else turned up?)
Conclusion: Confusion. Am I supposed to try the same thing another three times after the initial failure? What if I succeed before I've used up my additional tries. Can I try a series of different things? What if the fourth time doesn't guarantee a positive outcome? Do I stop altogether or continue until I do succeed?
Best just do things and make your own decisions about whether to persevere or not I reckon.
