Hello, could you show me how to switch the following real conditional sentence into the hypothetical conditional? I am not sure how to make „mustn’t” a hypothetical conditional.
If you want to be successful in what you are doing, you mustn’t be lazy.
If you wanted to be successful in ...
Can you finish the rest of the sentence for me?
Can we thus say:
If you wanted to be successful in what you are doing, you shouldn't be lazy.
#1 Can we use couldn't instead, maintaining the same meaning?
#2 Would the hypothetical conditional be:
[I]If you had wanted to be successful in what you were doing, you shouldn't have been lazy.
Thank you for dissipating the rest of my doubts.
Am I right to understand that if I speak about the present/future I say:
"If you wanted to be successful in what you are doing (in the future), you shouldn't be/mustn't be lazy."
and if I speak about the past I am to say:
"If you had wanted to be successful in what you were doing (in the past), you shouldn't have been lazy. "
I hope I get it right this way, otherwise, I am really hopeless...
