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?

[bhaisahab]

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?

They are both very odd. I can't imagine anybody ever saying either of them. "One doesn't know what one can do until one tries" is a bit better, but not much.

'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.'
