The bullet points are:

- Move to Boston

- Study

- Get a job

- at 27, come back and open a hotel

- then have kids 

She is saying... wow.. I had my whole life planned out in bullet points. Step by step. 

A whole life in bullet points?

Bullet points are short phrases or single words in a list that very briefly list things. The previous paragraph that starts "Oh, I had it all sussed!" lists all the items that this person had planned for their life. The phrase "A whole life in bullet points" can be suggesting that her life plan was not very detailed and has not been thought through thoroughly. This is then emphasised in the next paragraph that lists her new bullet points describing how her life turned out differently to her plan. E.g.

My Life Plan:

-Go to university

-Eat

-Study languages on italki

-Marry a beautiful Korean girl

-Grow old gracefully

-Die without causing a big disturbance to others

You can see how bullet points are not necessarily whole sentences or can be just one word and they are are quick way to show information in a brief and not very descriptive way. This is what style the person is referring to.
