I keep running across this sentiment, and although I don't have kids yet, is one I intend to take to heart.
"Quality time" is largely BS - making time for a piano recital is pointless and can barely make up for the time if you miss the fun and general bonding the rest of the time.
I remember the times sat eating dinner on the sofa in front the TV having a laugh with my parents more than the "hero" events like sports days or plays.
If you care about your kids and you're pretty stable (obviously, if you don't have money for clothes and food things will be different), just be there.
