Think about what you want to accomplish in 2 to 3 weeks. It can be beneficial to dream about your transformed body in a year’s time, but only in tandem with achievable short term goals. Otherwise you will lose sight of the light at the end of the tunnel.
Remember that Rome wasn’t built in a day, and you won’t lose all the weight in a week. Focus on the here and now. Find a program, such as The 3 Week Diet, that focuses on the coming weeks. Use that time to build good habits, and you will be prepared for the future months.
