VIDEO: 7-year-old Novak Djokovic lays out goal to be No. 1 in the world

Rarely do we fulfill the dreams we have for ourselves as young children. (If we did, there would probably be a lot more astronauts in the world.)

Novak Djokovic is one of the rare exceptions. Just before he won his sixth Australian Open on Sunday, footage was unearthed of a 7-year-old Djokovic talking tennis on Serbian TV, the germ of greatness already taking root.

Though his goals weren't modest, they proved to be reachable, and then some.

Djokovic has been ranked No. 1 for a total of 184 weeks, and counting.
