A beautiful life? Hmm.....
This is a very hard question, as it is difficult to answer.
My version of a beautiful life would be financial security, while doing something you love. I love knowledge, and I would spend the rest of my life in college, but that doesn't pay the bills.
I also would guess that a beautiful life would include good relationships, that is with yourself, your friends, a significant other, and your family.
A good relationship with yourself means that you love yourself and maintain a harmonious balance mentally, physically, and spiritually. If you don't love yourself, then you are not balanced, and you will never achieve anything until you achieve that balance. Mental include emotional as well as knowledge. Physical is keeping your body fir and well nourished, and Spiritual, means your faith, or relationship with a superior being.
I put relationships with your friends before the significant other and your family, because they can become your support, your soundboard, the people who are similar to yourself. Let's face it you have friends with similar interests or you wouldn't necessarily be friends. They can be your strength when you need it, and the kick in the butt when you need it. They learn your secrets, and you keep theirs.
The significant other comes before family because often you will share your life with that person more than you will with your family. If they become your best friend, then it becomes truly rewarding.
So what is a beautiful life, when your emotional, physical, spiritual, financial and relational needs are satisfied and you achieve true happiness.
