Max Stirner's, the man who enraged Marx to write more pages in response than his (stirner) total sum of work, The Unique and Its Property (formerly Ego and Its Own but that was a poor translation; attatched below) and his ideas personally captured me. He took arms against all that is sacred—against God, religion, the State, morality, and Humanity. I know that he only survived due to internet shitposts, but genuinely it will set you free. Keep in mind he makes a mockery of his contemporaries and hegelian dialectics in Part 1 Humanity.
Stirner's a predecessor of Nietzsche and it is speculated that Nietzsche read him though Nietzsche never mentioned him himself. I personally prefer Stirner over Nietzsche due to the fact Stirner is an nihilist where he proclaims the 'creative nothing' rather than Nietzsche's ideal of being an ubermensch (i could not care less). Perhaps this criticism is from ignorance; i don't know. Anyways...
Interested? I'd suggest reading his first chapter 'I have based my affair on nothing', which summarises his entire book. Then I'd suggest to read Stirner's Critics (attached below also), where he is clear with his words without his sarcastic manner in the former book before tackling the rest of the book. I think you could skip the entire section of 1. Humanity
except for
1.3.4. Postscript followed by chapter
2.x. onwards then go back. However, you can just read the entire book from beginning to end.
