How to take responsibility when working with a group.

So something that I just realized about myself, was something awful that I was doing. So let me explain. I am part of an online course called Desteni I process, and part of that course you get a buddy. This person helps you out by explaining things that might be confusing about the material. So before working with the course I spent many years trying to figure out the Desteni tools on my own, or least never speaking directly with someone on my experiences, and then listening to someone else, so like a conversation. So it was a very individual or solitary process. So within that I found some cool things. However, when I did work with the course there was something unexpected about me that was sort of revealed to me today. So throughout my life I had always worked on my own, and whenever I did work with others, I found them to be incompetent, usually, so I was very harsh to them with my criticism. I did change my attitude to some degree when working with others and their performance was not as good as it could be. Anyway, so for me I find myself automatically blaming others for the performance that we created together as one group. What is interesting to me, is that when working alone, I place all the responsibility or blame on myself, and when working in a group I sort of divide this responsibility. The consequence is that I place less responsibility on myself, which is the problem. It is better, or best actually, to place full responsibility on myself for what I can do, and how I can affect the outcome, in every situation. So when I started working more directly with the Desteni group on projects or on different things, or even just having conversations, I was automatically/naturally dividing up the responsibility, which made me weaker from a certain perspective. From my perspective this was something preprogrammed within me, which can be effecting many other people as well. To when working in a group of any kind, whether for a school project or in a job, the tendency to divide up the responsibility, which seems normal or ok. However, isn't it better for everyone to take personal responsibility for the total outcome of the work/project to make sure it is the best possible outcome? For me, this is obviously a yes. Because when I do this, I do this. The only person that would say no is Ego, because ego wants less work, less responsibility. This is also what I would see to be the basis for an society applying the Equal Money System, that everyone takes responsibility for every single point, always, and to make sure it reaches its absolute perfection with its form and context. So I share this lesson because it applies to all of us, since we are all part of the same group here on earth. So lets be the best being we can be and learn to work in a group the proper way, which is to take absolute responsibility for the outcome and for oneself in who one is to ensure we receive the best outcome possible for all.
