Intimacy means knowing each other and sharing most coveted parts of your lives. The self-revealing behavior, when reciprocated well, forms an emotional bond which is hard to break. With continues sharing, this bond tends to strengthen over time and bring the partners much closer. Friendship is the first step to intimacy, so before you decide to get into love, make sure you both share good friendship.
It is not immediately obvious what it means to be successful in life. The term is used generally to describe a professional success, that is, a signal achievement at work, indicated in part, but only in part, by having made a lot of money. Sometimes success means preeminence in politics or science or sports in a manner that does not necessarily imply financial attainment, but rather public recognition. Those who become famous in the arts or by virtue of charitable acts or acts of bravery are thought to be successful also. Others speak perhaps less conventionally of successfully raising children and grandchildren. That is not what most people mean by success, but a good case can be made for that achievement being especially important; and different societies have regarded the work of bringing up the next generation as critically important.
