Yourself

Be yourself. If you don't, who will? Nobody. So be yourself.

Why be yourself?

• You will only be second-best, at best, at being somebody else.
• Claim your uniqueness!
• You are optimised to be yourself.

If there was a universally "optimal" personality that everybody should aspire to, that would be too boring. Unless that personality enjoyed everybody being the same. But without diversity, all of humanity's eggs are in one basket. Surely that would be suboptimal. Thus, I have proved, by contradiction, that there is no universally "optimal" personality that everybody should aspire to.

As a corollary, be yourself. (This is not a true corollary, but I can't fit the proof in the margins of this page - I haven't found out how to put text in the margins in this editor.)
