I think you must enjoy your life first before you get married. Explore, know more about your self, follow your dreams, do whatever comes into your mind. Do the things you can do when you're still free. But of course have your limits. Because once you've been married there will be things you can't do anymore.
Perfect statement. There is no point in getting married in the 20s, because once you get married, you will lose much of your freedom. If your wife is too possessive, then she may not even allow you to meet or party with your female friends. So my advice is also the same. Enjoy your life to the fullest, and get married at 40 or 45 years of age.
