The former Manchester United manager insists he prefers being in the game this time around than staying out for the month of July and August but will wait and make the best decision.
"The most difficult thing for me is to say no to the possibilities I have to work," Mourinho told Sky Sports.
"I have to be patient and wait for the right one, and the right one is at the dimension of what I am as a manager.
"I have to be patient and that's the most difficult thing. I have the impulse so many times but... I have to wait for exactly the right one.
"If you tell me a club in another country [wants] to fight to be champions, to build something special, to bring that club in that country to a different level, maybe [I would be interested]. Who knows? But my focus is on the biggest ones.
"Why do I say no [to offers]? Because the level of challenge that I want has not arrived. But with all the respect for the clubs and the possibilities I have, I think I want the right to choose.
"My friends tell me to enjoy your time, to enjoy your July, August that you never have," he said.
"Honestly I can't enjoy it. I'm not happy enough to enjoy it. I have the fire."
Since facing the sack by Manchester United last December, Mourinho is yet to land himself a new deal, eyeing a move to the top European leagues.
