I found this new concept of combining stoicism and machiavellism.
Stoicism is a lot about self control and detachment.
Machiavellism is about getting results.
But in many cases, self control and detachment bring results, hence the stoic Prince (combination of Machiavellism and stoicism).
The problem for Machiavelli is often miscalculation. If you place all focus on getting results as soon as possible, it is quite possible you rush and act too soon, and even ruin results.
The problem for stoicism is not enough focus on results.
The solution is a combination. You should focus on results, on achieving your goals, but you should also wait and be detached from those goals.
Stoic man simply doesn't care if he fails, and that is a big advantage which allows a more clear thinking. Machiavelli cares too much for success that it often seeks to get success as soon as possible.
Both are very strong goal oriented philosophies, which is why you need both. Stoicism teaches a lot of values which Machiavellism lacks. Machiavellism on its own appears more like some pure manipulator's calculation, while stoicism adds morality to the table, and adds more calm.
But both are correct in one thing: detachment is power.
Man who cannot truly fail in his goal is man who doesn't have a goal, or man who doesn't even care enough if he fails.
People are driven by love (their goals) and fear (negative things they want to avoid).
Stoic Prince should not be driven by love or fear in any real sense.
Fear nothing, love nothing, in any strong sense.
What you fear can be used to control you.
And what you love, can likewise be used to control you.
