Do not stress over the fact you are unable to make a career choice right now. And whatever you do...DO NOT, under any circumstances, let your parents pressure into any direction. Remember, you're the one living the life, using the time, and experiencing the consequences/benefits of your actions, not them. Don't become someone's vicarious "role playing game character".
Having written that, very think carefully about what Warrior74 posted.
What do you like to do? What activities draw you, or energize you? Do you find yourself often tinkering with machines, drawing inanimate objects, whipping up meals from scratch, studying animal behavior?
Keep careful track of your time for a week. Then at the end of the week look at your top three categories. That should give you a clue of where your attention and interest lie.
Get back to us when you've had some time to think.
Also remember this: the world is not limited to the job postings on the internet and your local paper. The old rules of school and work are more or less dead. You must find and focus on your own path. There's lots of resources to help you do just that.
For now, as you search and ponder, stick with the basics:
1) Your Body - Check the Health and Fitness forum to keep your engine running as close to 100% as possible.
2) Your Teeth - I can't emphasize enough how important it is to take care of your teeth.
3) Your Mind - Study the basics of history, scientific method, warfare, rhetoric, critical thinking, and success.
4) Your Morale - You're very young, don't be discouraged or allow your spirit to be crushed by the tiny minds and ignoramus' who run the world.
Be your own man, first, last, and always.
