Finding Balance

One of the hardest things that I face everyday is how to find balance in my life. If I'm focused on my family, my my web development/business, work, coaching and training lose their focus, and vice versa. I can always find some way to justify myself that where I am at is right. My focus is usually driven by motivation, not necessarily what is the right decision at the time. Obviously my priorities are family, coaching/business, training, and work. Yep, work is last, though very much needed to support my family. Often I justify that if I can get the business/coaching off the ground now, I will have more time for family. Suffer now and reap the awards later - not necessarily the case, but I certainly hope so. My logic is I want to put 100% into everything I do an dedicate myself to it 100%, but in reality, I can put 100% into it 30% of the time. Wouldn't change what I have for the world - I love the challenge and the fulfillment I have going to bed completely spent. How do you find balance?
