I've always been the kind of person to keep busy, if I'm not doing something I feel like I'm wasting time. I would always feel guilty if I wasn't working toward something, striving toward achieving something. I realized that for a long time I attached my self-worth to how busy I was, how much I was getting done during the day. I suspect a lot of people do this but have never noticed because they've never allowed themselves to slow down. They're constantly doing or planning on the next thing to do that they never take the time to just be.
Your level of success in life, your self-worth, isn't dependent on how much you've achieved or how much material you've accumulated, it's dependent on the amount of love and joy in your life and your spiritual growth.
