It's valuable to take stock of your life at the beginning of the year and decide what you want to improve in 2015. It is possible to get too enthusiastic and decide that you want to make too many changes. Maybe it is better to get clear what you can realistically take on and only work on one or two issues. This strategy is more effective because it prevents a sense of failure. Changes are often difficult to make and require commitment and persistence.
I wish you a peaceful 2015.
