When my plate is full: Job, school, work I set aside a 30 min hard workout to help work off steam. Even if you just walk for 30 min you can listen to vocab recording for school. Helps me feel double productive!
It can be done:
1 Cup of coffee a day
take the stairs
If you have a day off do Yoga!
Drink more water
Vending machine are evil ( it may be hard but stay away)
Plan, Plan Plan ( I save money by bring snacks to work and school)
No regrets, if you have an off day or meal acknowlege it then move on.
