when i thought about the things i regret; the
big things; they had one thing in common...i didn't follow
my heart/gut/instinct*. IOW i had 2 or three options, one of which
i felt was the right choice, and 1 or more that others, parents, friend etc. thought were better choices. and i went with someone else's idea of what was
right. there are only a couple of times that this has (probably) affected the overall outcome of my life, but i do think about what it would have been like if i had _____'d instead. usually only when i am in a depressed mood. overall i feel like i am a very lucky person however in that i learned from these 'mistakes' and therefore want to teach my daughter to trust herself above all others (even me!) when it comes to something she feels is important.

OK, so there have also been a lot where alcohol was involved, but since i can only remember the good parts 
they're not really regrettable
