However, I am so tired of projects where endless discussions happen between my partners and me because we didn't agree on one leader to take final decisions.
I realize that this is a common issue, and one I have faced myself. However I think if aparatus are agreed upon specifically to navigate around these issues (for instance a vote system) then it will mean they are avoided. Whenever I have faced this problem it's always because no decision making procedure has taken place. Heirachy is, in this context, a decision making procedure.
In comparison, my real day job, with a boss who exactly know when to take decisions or when to let me do as I think it's best is so much easier and more efficient!
In some ways I think this is true but in many ways it is wrong. Many people despise this kind of working arrangment (although it is clear you're happy with it) and find it arbitrary and frustrating. And to quote Jantelagen 'you're not to think
you know more than
we do.' By coming to collective decisions the expertise of all members is taken into account and all members have an equal role in deciding what they work towards collectively.
(Edit: I'm sorry, I understand you didn't want to start a debate about the feasibility of your project, but rather look for partners... I just thought I may warn you, even if it could turn to the better (or, at worst, I could just let you do that mistake if it turns out to be one, and learn from it).)
No, I appretiate it, you didn't just say 'you're idea is shit and you're an idiot'
Constructive criticism is always (well usually) helpful
