Yes, and I was not wanting to juggle it like that right now. I can see that some enjoy that game. My scores cannot handle it right now. Perhaps in the future.
I don't enjoy the game even one little bit, however, managing three cards to keep reported balances low (or zero) along with a single SSL is a no-brainer and takes very little juggling; it is also just as beneficial at "fattening" one's file from a score perspective as having lots of cards. Speaking of the folks with dozens of cards, I agree with you, playing the game from that perspective is waaaay too much work for a couple hundred dollars and a few FICO points of gain.
Long story short, get three good "rewards" cards, even if you need to start them out as secured, keep them at low/no utilization, open an SSL and pay it down under 9%, and then hit the garden and watch your scores and history grow. Simple as that.
