i had to learn how to be LESS open. that's the direction i had to go in in order to grow. so, i can tell you by this experience that i found the middle ground by being selective about who i opened up to, and until i knew enough to be sure, i would open up about everything except
what i wouldn't want spread around. in other words, if i didn't want someone else
(other than the person i was talking to) to know it, then i'd keep it to myself. otherwise, i let it fly. anything. opinions, thoughts, feelings, tastes, hobbies, everything. but, i keep that 'line' in mind.
i was burned far too many times and learned the hard way.
sometimes, i still screw up though. *sigh*
i certainly wish you all the best.
