If you feel self-love and respect, then every aspect of your life should be serving you. This is not selfishness, rather self-mastery.
Most people are being run by their minds; but you are the boss and you should choose the thoughts that serve you. If you own a company, your life should not just be about paying salaries; are your employees serving your life while you support their lives?
If you own a second car or a vacation home, that asset should be serving you instead of burdening you. Your relationships should be the same–take a piece of notebook paper and remind yourself of all people who drain you versus all those who nourish your Soul. Give priority to the second group.
In terms of your material life, only purchase things that have a high joy-to-Dollar ratio. For example, you might buy a puppy dog for $1,000 and receive fourteen years worth of love and nourishment. Here then, the puppy has a very high joy-to-Dollar ratio.
Give of yourself, but also take what the gift of life offers–you deserve it!
