When you put too much on your plate, priorities get mixed up and you spend time on things that push you away from your goals, and less time on things that will get you to where you want to be. You only have so much energy and so much time, so my question for you is:
Where is your focus?
So what is your goal? What are you going to change? 6 months from now, 12 months from now, 5 years from now, where do you want to be?
Set your goals, stop doing the things that don't move you forward, and prioritize the things that will take you towards what you want to accomplish. You want to be in shape? Make it a top priority! Want to be healthier? Make it a priority!
