Now, if we simply follow the feeling, we are, like as not, going to wake up one day and discover that we hate the person we are supposed to love. The hormonal drive is the drive to mate and procreate. It is never about compatibility. So, a better approach, when feeling the first flush of love, is to also engage the brain and the soul, and explore who the person is. Never attempt to change anyone.
People are who they are.
People can choose to change some behaviors to make for smoother sailing, but we are who we are at the core of our beings, and that can't be changed. Never, never, never, become intimate with someone with no mentor. No matter what excuse they give. When you meet people with whom you really connect, the passion of that connection beats hormones every time. We can say the same about relationships with people you work with.
