Well Avatar I would suggest that your father is both right and wrong (although he's wrong for the right reasons
).
He's right to say that you shouldn't concentrate on love as your sole goal in life, especially at such a young age (since you're still in school I assume your <20). There is much to be experienced as a single person in this world that is worth doing. Travel, Adventure, Many many women in every color shape and size, and living your life with responsibility only to yourself... it's all worth experiencing in my opinion.
On the other side, your father is trying to get you to focus on your career and long term success. This is how ANY father will try to get his kids to walk down a path with the highest probability of yielding a successful life. BUT... Money and Career do not necessarily a happy life make. My career is going gangbusters right now and yet my life is in as tough a spot as it's ever been. Always remember that your first responsibility is to be true to WHO YOU ARE, and that there are as many miserable rich people as there are miserable poor people.
Staying in shape is a worthy goal... but don't do it for someone else, do it for yourself.
Having money gives you many options, but be VERY suspicous of any woman who's too enamored of your wallet.
I like the term "constructive self-interest", do things for yourself that make you a better person, or enrich your life... not to attract a partner to an illusion of yourself you've constructed around all these THINGS.
Finally... regarding LOVE. Always be aware that what we all as youth think of as idealistic LOVE is a hormone induced illusion. It's a cruel trick our bodies play on us to try to get us to PROCREATE. It gets us to choose a partner with the best of intentions, and go about building a nest together. It also quickly fades, there are as many song's out there about this part of the game as about the fun part. TRUE love is HARD, it's dedication to another when you can plainly see all the ugly in them, and you know that they can see all the ugly that you've tried to hide from the world. It's staying when EVERY FIBER in your being is screaming at you to run. It's living with someone that you occasionally HATE, occasionally LOVE, and VERY OFTEN want to strangle and hug at the same time. In the end it's much more powerful than the hormone induced version, becuase its REAL, it reaches into you and changes you more than you could ever imagine changing... without so much as a "by your leave". Don't jump into it lightly, and don't do it purely based on some feeling of "True Love"... do it because YOU'RE ready to take everything you know and are, and turn it upside down.
