Simple - don't shave.
Anyway, it's true that some people have better chance of growing
facial hair due to their genes.
As for me, even if I shave in the morning, I get a stubble by
bedtime. Right now I've got a goatee - and I intend to keep it. I
only shave my cheeks, sideburns and jawline every morning, and trim
my goatee once a week.
