How to make goals

A mind troubled by doubt cannot focus on the course to victory.
           -- Arthur Golden, Memoirs of a Geisha

Now this is very true. But don't forget one thing: Almost all the goals are goals in the Ego's world. The dream world. And they won't make you happy.
And further, the ability to doubt is essential to rising above the beliefs which keeps us trapped in this material world. People who never doubt anything may become emperors, but they don't meet god/Source.
