Usually, making excuses is just something we can get away with, rather than challenging or changing ourselves. If you want to change and you want your life to work at a level you've never had before, then take responsibility for it.

You've been provided with a perfect body to house your soul for a few brief moments in eternity. So regardless of its size, shape, color, or any imagined infirmities, you can honor the temple that houses you by eating healthfully, exercising, listening to your body's needs, and treating it with dignity and love.

You're creating it all. Nobody else is doing it to you.

Enjoy the moment, because that is all you have. You never are going to arrive someplace else. You are in a constant state of living in this moment, and that is the only arrival there is. In fact, you will arrive when you stop trying to get someplace else.

See the Light in Others, and Treat Them as if That is All you See.

If you subscribe to the notion of God as being separate from you, than you will always be lost, because you can't even trust in your own untrustworthiness.

If you refuse to change your job (if you don't like it), the only sensible thing you can do is practice loving it every day.
