I am not the best writer on the block, but I been working on a self quantification essay. It is of interest to lesswrongers since it is about It's about applying epistemic and instrumental rationality to self improvement in the form of running scientific experiments and data analysis on one self.
If you have any criticism or comment, let me know. Also, it needs grammar fixing since I suck at grammar. Thanks.
Be advised that the essay is undergoing continuous revisions. Some of the content may change drastically.
