A 2015 study published in The Annals of Behavioral Medicine found that pursuing your passion both lowers stress and contributes to greater happiness over all. Researchers found that participants who engaged in hobbies were 34 percent less stressed and 18 percent less sad during the activities, as well as for some time after. Laura Vanderkam, a productivity expert, advocates finding time for yourself as a means to greater happiness over all. "Life just feels better when you have things in your hours that you want to do," Ms. Vanderkam said. "There's moments where time almost has no meaning because we're so happy about what we're doing. The more time you can spend in that zone, the better life feels." We're all busy. Most of us feel as if we can't cram anything more into our schedules. But Ms. Vanderkam wants to dispel that idea. "When you say you don't have time, what you're really saying is, it's not a priority," she said. To figure out where extra time lives in your schedule, she recommends thinking of time in weeks, rather than days. A week "is really the cycle of life as people actually live it," she said. If you're prone to procrastination, start small and specific. Procrastination often happens when we get overwhelmed and stall before we even start. "Taking very small steps is key," Ms. Vanderkam said. "If you take small steps repeatedly, they really do add up. Say, I'm going to do just three things today. That's 15 things per workweek; that's 750 things in a year. If you do 750 important things in a year, that's a pretty good year."
