Lost? Try Modeling!
History is full of people who achieved amazing things by sheer will and persistance. If you think you cannot attain a goal you have set for yourself, have you tried picking someone in history or someone in the working field that you want to be in and looked at how they fulfilled their dreams? The path is already there for us. Look at how others before you got there. MODEL yourself after them. If you have not read Benjamin Franklin's AUTOBIOGRAPHY then I suggest you do so. When one looks at how someone else achieved success, you will see that there are 'habits' of highly effective people that you too can use to get what it is that you want.
