<prompt> Human: Ill try keep this short and sweet.My summer holidays are about to begin and my mother has just offered me the trip of my life. That being, go to America San Diego for the first time for 3 weeks to visit old friends. This would be 1200.Or I can choose not to go and have some of that just for myself 800. Do I deny myself this holiday as Ive never travelled outside Europe and am 18 years old.I have read a few books on stock exhange investing... THis would probably be the only oppertunity I get in at least 5 years.  <response>: Look at it this way...Unless you are a savant, investing 800 will bring you no significant return.Traveling abroad, however, provides the opportunity for once in a lifetime experiences. Looking back, 30 years from now, do you think you would regret investing a relatively small amount of money or would you regret missing a potential adventure?Leave the investment worries for when you begin your lifes career; until then, live.
