"If I didn't set high standards for myself I wouldn't be studying now."

[Rachel Adams]

Have I used the second conditional correctly?

Is my sentence correct? Can I use "now"?

"If I didn't set high standards for myself I wouldn't be studying now."

It's okay. I initially read it as "If I hadn't set high standards for myself I wouldn't be studying now," which is more natural and probably expresses what you have in mind.

If I use past perfect, it's the third conditional with "would have and the past participle" but I used the second conditional. If I use the third conditional, can I use "would" with another verb instead of "would have" with the past participle of the verb, I mean with past perfect? I see that you used past perfect with "would"and infinitive instead of "would have and past participle.

GS's sentence is an example of a so-called mixed conditional.

But can I still use the second conditional in my sentence? Isn't it wrong? The idea is that the person already set high standards.

GS has already said it's OK.

The past perfect is the right tense to express that. With the past simple, the sentence means you continually set high standards.
