"Decisions Determine Destiny" 

This quote means ever decision you choose has a consequence. Every time  you choose the wrong there is always something that happens after. You never know you might get caught or there can be a huge reaction of what you did. Maybe you can even change the way you think be having more percussion about your decisions. In other words the chooses you make now will affect your future and you will regret making those chooses. For example lets say you take drugs. That can affect your future because you can get some type of a disease. Another example is having unprotected sex. You need to take care of your body because than you create a baby you didn't want. have protection before making those chooses. Also dont make decisions you will regret.
