How do you like this sentence? Do you think it's too hard to understand?

- John enrolled on enlisted in/joined the navy, but after a day he realized that what he had done was not actually what he wished/had wished.

It's not the number of past tenses that's strange, but the meaning. I suppoose the underlined verb is best as 'had wanted'.

I imagine that Navy life was not what he had expected - something rather different from what you wrote.
