I love people, and I want to encourage my Brothers and Sisters to do their personal best...I have no desire for authority or position...
That is a wonderful place to be. You can be encouraging to your Bros and Sis without title, position, or office. Having no desire for authority or position will make you more effective than if you had the desire for prominence. Why? I believe you have answered that...
I find people that are position minded extremely difficult to deal with and to be around.
People will appreciate you much more without the negative attitudes that you yourself see in others. Most men in JW positions of responsibility are position minded, they lack humility, and they will only go by the letter of the law....the law being whatever the Society says whether it is kind, loving, shows fellow feeling, and is Scriptural or not.
You appear to have true humility and can see problems within the Organization, at least to some extent. If you are reading Franz' book(s) you will get to know many things that are wrong with Watchtower.
Perhaps your desires to help people could be applied by helping JWs to see that the Watchtower is not 'God's spirit directed organization on earth' as it claims to be.
Continue learning about the Organization by putting it to the test, read about the problems others see in it, learn it's true history. Don't ignore issues that raise serious questions. In time, you will see what you should be doing.
You are at a cross roads.
