The good news is there is a map. Unfortunately, as you get older, your eyesight gets worse and you have more and more trouble seeing the map. It doesn't matter, though, because the map is in another language and – like driving in Europe - the map has no relation to the territory. Luckily, from time to time, there is a rest stop with a REALLY BIG MAP. Look on the map. If it says, "You are here" then you are probably in love.As for love, I have no idea what I think about that anymore and I've had a couple mini-internal-breakdowns trying to figure that out lately.
When I realized that I couldn't trust anything that I thought I knew about love, I was in a better position to actually start loving. Not that I have a clue even now. I still like what I said here when someone asked me how do you know you're really in love:The bad news is love is a vast territory.
