Why can't we all just be Well-beings?

I wish I was a finely tuned piece of machinery, but I am not. I try to be, but maybe trying just isn't enough. Some people are blessed to have no pains, to have a body that seems to be invincible. I on the other hand, for a person who is only 36, feel like I have been put thru the ringer sometimes. I have back problems, I try to not let that get in the way of going to the gym most days of the week. I have worked hard all of my life and my 20's have caught up with me. So on a scale of 1-10 I rate my physical well being as 5. Psychologically, I think that I am very in tune with who I am and my purpose here on this rock. I am meant to nurture and teach, that's what I do best, especially children. I have a job that allows me to be a big part of children's lives and help them to grow into respectful adults. I just don't take things too seriously, unless they are important to me. I don't care if some milk was spilled on the floor, or if I don't make that much money, what's important to me is my family and my health. So, I guess I can give myself a 7 on the psychological well-being scale, not a 10 because we can all do more. Spiritually, I need work. I tend to put daily life ahead of myself. I do not let my self do the things that I enjoy very often, rather, life gets in the way. I have a family, a job, pets, there just seems to be little time for me. I feel selfish when I do for myself and often back down when it comes to some me time. I would rate my spiritual self a 5, she needs work.
