Every year Chris Brogan posts his three words for a new year. many others and I have followed his lead for the past three or four years. They helped me a lot. My words for last year were “passion”, “focus” and “delegate” and I stayed true to them. This year, 2013, my goals are more personal and less professional.

FOCUS

Focus is making a repeat appearance on my list this year because I’m too much of a multitasker. The problem is that I have trouble finishing one thing with so many things calling me. When I was working as a writer, all my projects were handled via a schedule, I’m putting a fitness and housekeeping routine into my schedule.

HEALTH

I get so busy taking care of everyone else, and I forget to take care of myself and this has to change. My health suffers and my weight suffers. I have to get my health in check , not only for me but because I promised my 9-year-old son. I’ll make good food and lifestyle choices. I miss being thin, and it’s time to get it back.

CELEBRATE

What good is having it if I’m not taking time to enjoy it? I have a wonderful job, a happy family, and so much to be thankful for. So how come I spend all my time working? Last summer my family took our first vacation in four years, the best thing I’ve done for myself and my family in a long time. This year, I’m making sure to take time to enjoy life and celebrate its many blessings.
