How long till my beard grows properly? Please help?

Right, so I'm really frustrated because I really, really want to grow a beard.

ALL, yes ALL the males in my family can grow full beards, except me (for the moment at least). As you can see in the picture, a beard can be grown everywhere under my chin and throat. My beard grows pretty well on my top lip as well.

However, I don't know if you can see properly, I've got these little hairs poking out of my cheeks. I don't know whether these will get longer and fuller or not (?)

I've had a lot of people, mostly men with full beards, tell me that I'm on my way, and that I'd definitely suit one.

What can you tell me?
