The greatest skill for student success in high school

In my opinion the greatest skill for student success in high school is initiative.  If you don't know what initiative is, it is the ability to be able to have the mind set to get work done, and sometimes it is even enjoyable to get it done.  To be able to get through high school teens have to have some level of initiative, mostly to get work done, but to also get work done fast.  This is a skill that takes a while to completely master, but once it is picked up it can almost never be lost.  I know you are reading this and asking yourself what about the people who don't master or never pick it up, for them school becomes very hard and some might not even pass.  It is a very important skill for student success and I haven't completely mastered it, but I really need to be able to know how to do it.  The fact that I don't have initiative has made it hard for me to complete some classes.  Initiative is a very important skill for student success.
