If you voluntarily decrease your income, the court is not likely to reduce your support unless you can show that you are doing something like going back to school to further the child's best interests by increasing your income long-term.. Dropping higher paying IT to teach does not fit that scenario. You can certainly go back to school, as long as you still pay the same amount of support.
The court does not care about your prior personal plan/dreams. Their message is that you have a child and the child is helpless and thus you can no longer live life as you would have as a single person who has no child. Overall, society's current message is that an individual's needs/desires take precedence over anything else, so it can be quite shocking to confront the world of child support law, which will quickly disabuse you of that notion.
