How Do I Become Anything?

First of all,decide on it and practice, practice, practice. If you want to be a philosopher and wise Epictetus said:

We ought to learn that there is a God and that he provides for all things: also that it is not possible to conceal from him our acts, or even our intentions and thoughts... (We) must with all our power try to be like him. If the divine is faithful, man also must be faithful: if it is free, man also must be free; if beneficent, man also must be beneficent; if magnanimous, man also must be magnanimous; as being then an imitator of God, he must do and say everything consistently with this fact.

 Whatever we wish to be, we must learn the skills of that thing, whether it be music or art or coding and be consistent in our learning and application. 

In addition, it seems to me, we would also do well to seek wisdom and a relationship with God.  There are many writings and teachings about this, of course. Epictetus writes succinctly. His words can add to what we know or seek to know. 

To me, if I say I am something or other, but do not do best  practices of that thing, I am not really what I say I am.. I am a phony, sloppy, an imposter. 

I think that is one of the reasons people have fallen away from religious groups, are disgusted with politics, and don't know what to do or how to find a genuine, congruent teacher. So few practice what they preach, often even do the opposite. 

If we want to turn the world around, we need to embody the qualities that we desire in our leaders, practice them, get more and more consistent, and then, only then, teach others, lead others. As is often said, be the change you want to see happen.

You can do it. God has led you here to these words, in this moment of time. Hear them in your heart and begin.
