Ask yourself this.
Who do you think about when you wake up, when you go to bed?
Who do you dream about?
Who can you not wait to share with what happened to you today? Your excitements, your passions, your dreams, your sad days?
Who do you turn to for advice, comfort, energy?
Who do you wonder about how they are doing and what they are doing?
Who do you think about?
That is who you care about and love.
Put them in your life, and be free to do so. And keep them there. For they are valuable to you.
