What advice would you give to a young man who is trying to find a keeper(better half)?
Figure out what you must have. It's tough to be with a vegan if beef barbecue is your thing. Similar attitudes about money/savings/where to live/religion/how to raise the kids also can have a huge impact. It’s not that everything has to line up, but you should at least know your red lines.
Then learn how to dress, learn basic manners (my pet peeve is table manners), look at what you can do to be a kind person, and learn most of all to listen.
Oh, and get interested in something other than women. The most interesting people are those who have a passionate interest in something else.
