Starting something new is easy. Sticking with it it tough.
This happens no matter what we do. It happens in our relationships (ever notice how high the divorce rate is?). It happens in the middle of a school semester or in the middle of a project at work. It happens with a new hobby or creative endeavor. It happens when we work out.
How should we deal with dwindling motivation?
1) Admit to yourself that you are going through this phase and that it's normal. Lying to yourself, blaming yourself or forcing your way through will most likely just burn you out.
2) Take a step backwards... but don't quit your habit. If you have been studying every day for an exam for several hours, maybe you need to cut back for a while. If you have been exercising for one hour every day, maybe you need to take one day a week and just do 15 minutes of light exercise like walking or stretching. Stick with the habit, but go easy on yourself once in a while. Even five minutes is enough to keep the habit a habit. The important thing is to not give up completely.
3) Brainstorm ways to spice up your routine. Perhaps you are trying to eat a healthier diet. Explore a new supermarket or cook with a friend. Or perhaps you are sick of studying... A change of scenery might help. Try studying outdoors at a park on a nice day. Sick of your work out regimen? Try a new activity today.
4) Catch up on the Zzzzzs. If you are exhausted, you probably will not be able to sustain your new habit.
5) Tell somebody how you feel. Ask them to be your cheerleader. That's right, ask people for motivation! And help them by giving them some motivation. But don't fall in the trap of making excuses for each other. Lift each other up and cheer them on!
6) If all else fails, look into your child's eyes, and think of what kind of role-model you want to be for them. Then show them how great they can be by doing great things yourself!
