Sacked in December, Mourinho has used his spell on the sidelines to prepare for his comeback.
He told beIN Sports: "What I have in mind is that I would like to be back in June for a new club and a new pre-season.
"I know what I don't want and that is the reason why I have had to say no to three or four different offers.
"I know what I want, not in terms of a specific club, but the nature of the job, and I am going to be waiting for that.
"In this moment, I miss nothing at all. I am two-and-a-half months without work, but I am preparing for the next one. It is not like I am on holiday or I am bored with nothing to do.
"When you are working every day with six press conferences, three matches a week, and all the problems you have day-by-day, you have no time to take care of yourself. Now, I have these months where I can come back even better prepared."
