The Portuguese coach is currently gearing up for his second season in charge of Tottenham after taking over from Harry Redknapp at White Hart Lane last summer and leading Spurs to a fifth-place finish.
The 35-year-old manager also revealed his desire to compete in the Dakar Rally.
“My passion for football makes me live it very intensely over 11 months and dedicate myself to that,” Villas-Boas told O Jogo. “But life allows you to enjoy other things.
“For me, there is a limit and, in the next five to 10 years, I will quit coaching.
“I do not know where my career will take me. What I do know is that it will not last too long.”
He added: “To compete in the Dakar Rally is a lifetime ambition for me and is something I know I have to do. It went from a passion to an obligation.”
