If you are not shy and you are a hard worker. Test yourself and your self reliance skills.
1. Buy a roundtrip ticket.
2. Start in [I suggest] Barcelona.
3. Hitch to the Med coast.
4. Find work in the many greenhouse and farm "factories"
5. Make enough to go to your next Work Place "Vacation" say Italy.
Work your way around Europe. Plan on being there for 3-4 months. If you can do this you will be the world's best traveler, and learn more about the people and culture. Think of all the great writers, artists and poets who took walking tours. Don't be surprised that people will take you in in rural areas, and give you food and lodging for work.
Keep a journal, and make film clips daily. When you return you can sell this stuff and then take a luxury trip when you are more mature that you will really enjoy --having first learned European life from the grass roots on your first trip.
