Family, Business, Career and volunteering for non-profit. How should I balance this year?

I am a female, Chinese descendant and born on June 15, 1967 at noon - the year of the Sheep. This year, 2015 is the year of my animal. I am a mother of 3 kids: one in college and two in high school. I am thinking of expanding my business and bring some partners. What advice can you give? I am also on the leadership of the non-profit organization for 1 year (chairperson). I worry about my senior HS kid to get accept in college. I am finding it is tough to balance my work, family and health right now. I need some advices from you on the future of this year. many thanks,
