You want to improve yourself next year? Here are 2 simple things to do.
Decide and devote.
Decide what you want to change. Decision is a one-time action. Once you have decided, devote time and effort into that decision every day.
Best is to write it down. Then every week, look at that written decision. For some people, they feel motivated. For others, they feel guilty. Either way, I hope they spring you into action.
