Set your goals
Goals need to be specific, measurable, attainable (and action-orientated). Goals also need to be relevant (and realistic), and time-bound. Goals using those components are often referred to as SMART goals.
One of your roles is being a student. An example of a bad and good goal for this role are:
I will do more homework. (This goal is not specific, measurable or time bound.)
I will read chapter two of my chemistry textbook and complete one practice problem set before next Thursday’s class. (This goal is specific, measurable, action-orientated, realistic, and time-bound.)
