It's the journey that matters most, and the mystery is just part of the fun.
I just started as a miscellaneous product reviewer, and I thought, "Why stop at that?" Sure, reviewing whatever's available can be fun, but the race gets tough when the most useful merchandise come along. It's difficult to review a refill or spare part for an item I don't own, know what I mean? So, I figured I should work towards specialized merchandise, games, apps, tourism, food, real estate, and theories about some of my favorite shows.
Life's full of niches, so why be limited to just one?
