Some people play in a band. Others garden. Golf. Skiing. Yoga. Fishing. Knitting. Volunteering. Long walks in the park. Whatever you do to achieve work-life balance, the data is clear: If it makes you happy, you will be 15 percent to 30 percent better at your job.
Hobbies are fulfilling, and fulfilled people make more productive employees. Hobbies unearth hidden skills, alleviate stress, unite you with others, and improve quality of life -- all things that will help you function better at work.
