I have not found any sentence using ~さえ~ば with more than one requirement. Let's consider the following sentence with 3 requirements
- I am healthy
- I have enough money
- I can speak English
to be confident. The sentence I want to say is as follows.
If only I am healthy, have enough money and can speak English, I am confident to go everywhere I want.
My attempt is as follows.
元気で、お金が足りて、英語で話せさえすれば、どこでも行きたいのは自信がある。
Is my sentence correct grammatically?
