Niche O.o

So it has been recommended to me by reliable sources that my best bet of getting this blog found as well as having success with this blog so I must discover my niche and focus on it. So far I am pretty sure my best bet will be video games, camping, wilderness survival, stealth, or woodsball (paintball). These are things that I probably know best and will be able and willing to continually post on. I highly doubt that having all of these topics together seems like a good idea so my best bet is probably choosing 2 or 3 to focus on. I'd ask you all for your opinion but so far I am the only one who knows about this blog... So asking would be talking to myself and I will be more afraid if I answer back. Sooo I shall leave it at that!
