You can prepare yourself to succeed in your studies.
Try to develop and appreciate the following habits:

Take responsibility for yourself
Responsibility is recognition that in order to succeed
you can make decisions about your priorities, your time, and your resources

Center yourself around your values and principles
Don't let friends and acquaintances dictate what you consider important

Put first things first
Follow up on the priorities you have set for yourself, and don't let others, or other interests, distract you from your goals

Discover your key productivity periods and places
 and p Morning, afternoon, evening; study spaces where you can be the most focused productive.  Prioritize these for your most difficult study challenges

Consider yourself in a win-win situation
You win by doing your best and contributing your best to a class, whether for yourself, your fellow students, and even for your teachers and instructors. If you are content with your performance, a grade becomes an external check on your performance, which may not coincide with your internally arrived at benefits

First understand others, then attempt to be understood
When you have an issue with an instructor, for example a questionable grade, an assignment deadline extension, put yourself in the instructor's place. Now ask yourself how you can best make your argument given his/her situation

Look for better solutions to problems
For example, if you don't understand the course material, don't just re-read the material. Try something else! Consult with the professor, a tutor, an academic advisor, a classmate, a study group, or your school's study skills center

Look to continually challenge yourself
