[Doctor Who] What is it with the Doctor's obsession with humanity?

Why does the Doctor's adventures/travels revolve around humans and Earth so much? What makes humankind so special?

The Doctor waxes poetic about humanity quite a bit, so he definitely personally considers them at least one of the most interesting species and actively wants to be around them. Two things also stand out about them:

1. Humans have more capacity for compassion, creativity, bravery, etc. than almost any other alien race shown, all qualities The Doctor frequently praises them for and often refers to as distinctly human. Even the 'good' aliens tend to be very one-note or severely lacking in some capacity.

2. Humans are the ultimate survivors. At the end of the universe, the populace will be almost entirely humans and mutant offspring. The Doctor will always be able to live among humans and seek their companionship at all but the most distant points in time.
