Actually, I see 2 good or 'not so bad' sides of being like this (this is in my own view thou I don't know if anyone would agree):
1. Most of us tends to be or is creative and/or intellectual. Some may not agree, some may not see it in themselves but like I said its in my perspective. Some/Most of the best artworks of different kind from music to paintings and such are made by "us". Not just referring to people with Bpd but people like us who's a little "different" from the rest. (trying my best finding "safe" words as to not offend anyone).
2. For someone who suffers from Bpd and has a more rapid shifts in mood (like me these days) if I became completely depressed and frustrated about something, it could or would only take a few min or so till my mood shifts to something better or feel nothing/blank. It may change again in another min but it saves you at times as long as you control urges when your in the negative part of your mood swings.
