Nobody expects you to have all the answers at 19, but so many people think they do. The beauty of this is that they also feel fearless, which can become stale with age. So when you finish high school and are trying to decide what to do next, remember that your choices are not permanent. You are not going to be the exact same you in 10 years. Take courses in college or a vocational school that sound exciting and interesting - not simply courses that "fit the grid" required by the school. Oh, I know the costs can be great, but how are you supposed to know you were born to be a scientist if the only courses you take are in the sports and recreation department? Do what you really love - even if it isn't a "money making venture" for your future. You will change, and so will your desires and interests, by the time you are 25 or 30, so make the most of it. Take as many courses abroad as you can - find a school that has this option and utilize it. It's a big world and when you only see the limits of our county or State, you are seriously missing some opportunities for expanding your mind and heart. Be bold and confident in your decisions. Oh, and be sure to be nice to your parents if they are helping foot the bills!
