Your physical state directly affects your psychological state:
- Eating a balanced diet, avoiding alcohol, and getting good rest will keep you from getting sick and missing study time. These will also keep you happy and motivated.
- Remember to eat regularly, at least three meals a day. Your retention decreases when you’re hungry.
- Exercise as much as possible, even if only for 15 minutes a day because weight lifting and cardiovascular exercises are proven to improve memory and reduce stress (which you will have a lot of with work and studying). You can squeeze in an intense cardiovascular work out by jumping rope or running on an uphill treadmill for 15 minutes.
