If we're posting words of wisdom, I can think of none greater than own late father's words, when I asked him if I should marry my wife (now 10 years along).
"Well......does the good outweigh the bad?"
"Yeah, Dad."
"Then realize, all the little things she does now that make you smile will make your heart sing as years pass. But.....
All those things she does that irritate you now will make you want to stab her with a salad fork in the future."
Dad was a sweet, gentle man, and said this for comedy's sake, but he was right. Things magnify.
