To my holy brother, I only come to add and agree with what has been written above. 


Firstly, when one is stuck in the PandM cycle, it is hard to feel the connection with other people. It keeps us in our misery mindset. 
That should be a first goal of yours-to get clean and free
(But even until that happens, the other things I will write are 100% relevant)

You wrote about feeling needed because you aren't an 'asken'
Firstly, I have many gripes with so called askanim. Many of them are money and power hungry people. Don't be like them. 
Also, you wrote how you can't give as much tzedaka as 'gvir' so you don't feel important. 
Well who says he gives as much tzedaka as he should! You claim to give tzedaka. Wow. You take your own money and share it with those that have less. That itself is a great thing. 

And now for my final point. 
Let's say that Mr askan/gvir/doctor etc was really helpful to others, but was not a good father/husband/community member. Would you consider that to be a good thing? 
Of course not. 
You know in your heart that the most important thing for you or anyone is to be primarily a good husband and father, to get up and go to shul in the morning, have a chavrusa, accomplish at work etc. 


What if you went to work, did basically nothing, accomplished nothing, lazed around, but made a good salary, would you feel good about yourself? I doubt it. 


Your main focus has to be yourself. Doing the things that are important. 
I'll bet if you wrote down a list of what is truly important in life, being wealthy would be very far down the list. Very very far. 


As a suggestion, if you want to feel more needed, get involved in your community. Go pack boxes for tomchei shabbos, join hatzalah/chaveirim/misaskim, find out who in your community needs help (new mothers, people struggling for jobs) and help them. 
If hashem didn't make you 6' 8", he probably doesn't want you to be a starting center on the Lakers. If Hashem didn't give you $100m, it's because he doesn't want your name on a yeshiva building. 
I think you've narrowed down what your fantasy has told you means 'accomplishing' and now you can't live up to your fantasy. 
That's only going to hold you back. 
I would love to keep this conversation going. 
May Hashem give you the eyes to see what is actually important in life and give you the strength to go out and accomplish it. 

This is in response to the post that stated that the Askan needs the Nebach, the Singer needs the crowd, and the ensuing conversation. 

I feel that the writer's point was missed. The nature of the world is that there are givers and takers. Most of us have probably been one or the other at some point in our lives. We strive and hope to be on the giving end, but if one finds himself as a "taker", or just not as much as a "giver" that he would like to be, he shouldn't view that as an aberration, but rather as a part of the earthly cycle. To take this notion even further, the premise that fulfillment will only come from being a big person, i.e. a Gadol, Askan, Gvir, etc. is what was being disputed. The idea that the only life worth living is that of a mover and shaker does a disservice to the 99% of people who aren't. Most people can't and won't be those things. They are still entitled to a life of fulfillment and accomplishment. 

That being said, I think Time2Win's point is still valid. He feels that he personally isn't living up to his potential and that he has much more to offer the world than what he is currently doing. He wasn't trying to say that everyone has to be a superstar. I believe there is a balance between feeling the need for self-actualization, as Time2Win expressed, and being content with our current position, even if it doesn't fit with our perception of what our potential is.
