Ryan, if I was 18 (now 66) and invested in ELTP I would turn a deaf ear to anyone who was talking about taking small profits.
At your age, you can afford to be more patient with your investments than most of us and get on with other parts of your life. Your investment in Elite has a distinct possibility of being one of the greater investments a person can presently make in the stock market given some time for things in Elite to mature.
Good luck with your investing. I think it is fantastic to see young people who are not afraid to take a risk, especially in a society that is becoming more and more of an entitlement society.
Whenever I see young people with your attitude, I am reminded of King David's military leader, Joab, who said to his men before a battle they were about to go into:
"Courage! We'll fight with might and main for our people and for the cities of our God." It is attitudes like this that made our nation great.
