I recall my mother telling me, many years ago, when I was born my horoscope said I'd have so many interests in so many different directions if I wasn't guided by a strong hand I'd spend my life jumping from one thing to another & never accomplish anything. I don't really believe in astrology. But this horoscope was spot on. However I wasn't guided by that strong hand & my horoscope was correct. I've never accomplished anything!

I have the same problem you describe. I don't know where it comes from, or what causes it. And unfortunately I also don't know what to do about it. Perhaps it has some connection with anxiety, which I also have always had allot of. If so, then such things as meditation, physical exercise & the other sorts of things that help reduce anxiety may also be helpful in reducing your "bran bounce"...
