"The Summoned Self"

The writer is discussing how and the various benefits and drawbacks of living a 'Well Planned Life" and a "Summoned Life." The writer believes a well Planned life is the best, maybe because that is what he did. He believes a 'Summoned Life' is just thinking in the moment, and therefore not very beneficial to the person. 
The writer organizes his thoughts very neatly and he goes to conclude why he thinks a 'Well Planned Life' is more beneficial. He kind of makes the argument biased by stating that he agrees with the lifestyle he thinks is the best because that is the course he took. 
But, other than that, his ideas seem accurate and are arranged in a way that the reader is able to very clearly understand each lifestyle before deciding on their own opinion of which is the best. 
He gets his information from the Harvard Business Review; a seemingly reliable source. He draws his information from the article before he states his opinion at the end. He uses the source to kind of describe a coming of age story to make the ideas more relatable to readers.
His argument at the end seems to be quite valid, but it also raises the question of bias. If he had not added his own experience to the piece, it would seem more believable; however, it does give it a nice touch. It all really depends on the reader's point of view and their ability to ignore the author's bias.
