Educate yourselves in something you love, or at least like.
Live your life as you want it first, then get married, if that's what you want, not the other way around. Don't get married to find yourself. Find yourself as preparation to getting married and then maintaining an honest relationship.
For example, if you come to the conclusion that you are most happy crunching numbers and solving complex problems, and that involves living in a big city, wearing a suit to work and carrying a briefcase into a big glass building every day, accept and embrace it. Alternately, you may find that living in the suburbs, preparing lesson plans and teaching eighth graders is more satisfying. If either of these or a million other scenarios appeals enough to you to make a life out of, make it happen early after college. Then, in that circle of personal and professional satisfaction, you may be blessed to meet someone in your circle that is not only compatible, but the one. You don't just have to be what you want, you have to exist in that want and see what the gods provide for.
The 6 pre-requisites of marriage:
-Educate yourself
-Date and be with lots of people
-Spend lots of time with a potential mate. Don't fall in love early, get past the infatuation and see what happens, then think about marriage
-Be over 30.
-Be established in your career and life's pursuits.
-Remember, this is just your Dad speaking.
Don't worry about marriage or sex or having babies. Worry about the relationships you develop by being true to yourself. If you're true to yourself, you will attract those that will stand by you because they value the same things. They will be the basis of your life-long friends, and one of them will likely be your soul mate.
Don't dismiss that voice in your heart. Sometimes it will disagree with what others are telling you or persuading you to do. That voice is unique to you, and the messages it sends are meant for you to interpret. Do what you will, but do not ignore that voice.
If something sounds too good to be true, it usually is. The only guaranteed formula for success in life is hard work and preparation... intellectually, emotionally, spiritually and physically...and the rest is luck. But if you're smart, you can stack the cards in your favor.
Don't invest in anything with too much readily available information. Don't expect to get ahead doing what everybody else does. Look at what everybody else is doing, then at least find a way to do it better, or better yet, do something extraordinary. (Example: don't build a faster train. Build an airliner.) If you read something in the Wall Street Journal, and get inspired to invest in something, realize, you're at least 2 million people too late. The early bird catches the worm, and he didn't need the WSJ or some TV advertisement telling him to invest in gold or rare coins. His instincts guided him. (Plus some hard work and preparation that got him there in the first place. See previous paragraph.) Opportunity is when preparation meets luck.
Your parents love you unconditionally, want the best for you, and would jump on a grenade for you. That doesn't mean they know anything about parenting, it just means they are going to do their best, and like it or not, that's all you're going to get. What you become is far more dependent on the decisions you start making as early as you are able. Luckily, some of your parents realize we are raising parents and adults, not children, and are allowing you to grow and experience what it means to be human and are not just an isolated ego-enhancing experiment for mom or dad.
Listen to opinions, but remember they are just opinions, not reality. At the end of the day, you decide.
Respect and use the rules of science. Science is not just a set of tools, it is a way of thinking, rational and unbiased thinking.
Fear absolutes and unassailable solutions. Anyone that claims to have found "the answer" is lying, or asking for money. Don't get ripped off. Scientists and Artists realize that every solution is just a step in the process to perfection. Don't presume the conclusion, you'll end up stale and trapped by others. Rather, embrace the journey there, and accept that there is no destination but the journey. The only truth lies in universal principles, and only a few are apparent. Live by those principles alone, combined with what the gods tell you. Do not listen to the exploitative religions, belief systems, weight loss plans, fast-money programs or other marketing scams that take advantage of those principles and extend them into servitude and revenue streams. At the end of the day, if you want to know the truth in the real world...follow the money.
Be true to yourselves. Make your life what you want it. Know that you are always loved.
