Goal orientation, as we all know is really hard. (I certainly know that!)
In order to set that goal, you need to ask yourself what you want.
For example, try looking in the mirror and asking yourself this:
"What do I want?"
Whether that question be for your education or relationship life, that one is always the one you NEED to know.
Once you know this, ask these questions:
1: How do I start my way towards this goal?
2: Is my goal healthy for myself and others around me?
3: How am I going to reach this goal financially?
4: How determined am I to make sure this happens in my life?
If your goal is career wise, you could always start by pushing yourself for a high GPA, looking for colleges, deciding what you should major in, what you want to be in a career, and how you'll afford it.
