(Disclaimer: This was written when I favored survivability more than self-actualization)
In my eyes, the ideal man would triumph over the absurdity of our repeatable existence, while accepting said absurdity and will not always find ways to escape from it, as every escape from it would be finite and limited, and you would always have to return to the External World once more to make a living.
They would be a nihilist, but not a negative one, nor a positive one. They would look at the Great Void but remain lightly affected by it, if at all. Their strongest emotion would be apathy, as apathy is an indication of mental resilience. They would not depend their existence on meaning and purpose, as every meaning and purpose can end before your life, and what would you do once you would find absurdity once more?
They would go to their work and attempt to do their best not because they want to be the best at it, nor to contribute to society, but to ensure their survival in a world with no definitive meaning or purpose, for they are aware that they are mostly a human resource in the External World, and not necessarily something greater than that, while among other people.
They would not wish to die, nor let depression take the best from them, as living is less painful and less harmful than dying, making living preferable.
They would not be tempted by money, fame, love, sex or power, as they would know that these are merely temporary things that can easily deceive one’s sense of judgement, and bring to their downfall once they depend their desire to live on these things, and on external things in general. Due to their low life-force, they are not easily tempted, as they wouldn’t see much of a point in reaching higher socio-economic state. They are in death-while-alive, making them more resilient against unnecessities.
In fact, they wouldn’t depend their life on anything but on the will to survive. That way they would not be easily disappointed, and when desperate, they would have the desire to overcome it and continue the daily struggles of the living, due to their will to survive and to endure, even if nothing special or significant awaits them in the future. They accept the monotony of life, because even if it’s philosophically absurd, it still fulfills the needs to live and to survive practically, while also being safer than an otherwise adventurous life, where the chances of death and unnecessary pain are much higher.
