- For Teachers
1) No one knows what one can do till one has tried
2) No one knows what one can do till one tries
How are they different?
'You never know what you can do until you try/have tried' and 'You'll never know what you can do if you don't try/haven't tried' were part of my childhood.
The sense was; ' You will know if you can succeed only if you make an attempt.'
