sneaky,
Good question, and it's one we get occasionally on the boards here but not too often.
When you're not in control of your own emotions, it feels like you're living your life on a roller coaster. You'll have moments where you have extreme highs and you feel like you're on top of the world... but then as easily as a few moments later, you can come crashing down. While the highs can be amazing, the lows can be absolutely devastating. Usually the highs are only brief, but the lows often last for long periods of time (months/years). Some guys never even really recover from the lows (unless they work on self-improvement) and end up living life in an emotional depression.
When you become advanced at seduction, there is some loss to the highs. You'll probably never really "peak" emotionally the way you did when you were at your highest point (probably with a girl you "fell in love" with). However, you almost NEVER experience the lows anymore. Your lows are extremely minimal, but you can still experience the majority of the highs. So you ultimately sacrifice the highest level of "good" emotion for a steady, high level of "good" emotion without any really bad, low emotions. If you're good with mathematics and understands waves, imagine that your "amplitude" becomes much smaller because your emotions don't vary so much. You'll ultimately be more happy, so there are plenty of "crests" in your wave, but they won't go as high as they might have before. However, your "troughs" are much less frequent and don't drop NEARLY as low.
The problem with emotional lows is that they usually affect all aspects of your life (including your friends, family, and career), so they can be extremely damaging. I've found that removing myself from being able to sink low emotionally (by understanding and becoming good with women and relationships) that I never have to worry about my life being turned completely upside down. That's not to say that I won't have moments where I'm slightly upset or disturbed by something caused by my significant other or women I happen to be spending time with, but I usually know how to resolve things in a way that keeps my mind at ease. And in the meantime, I'm able to enjoy all of the highs that are provided to me when I know how to handle women correctly.
Anyway, that was a bit of an in-depth explanation, but hopefully it provided some clarity. =)
