A. I recommend people never have -one- thing they do. Having -one- thing makes you dependent on the outcomes of that one thing, which will ebb and flow. Start putting energy in something else as well (I especially recommend strong relationships, or a physical activity pursued at the hobby level), and when your original project hits a low point, use your other activity to recharge.
B. Are they really newbie? Did they do 5 years of work in obscurity, and you just saw the point where they broke through?
C. Community glory tends to be a 'winner-takes-all-affair'. 8 people get 10% each, 2 people get %40 each. Try to live your life such that such long-shots are capable of enhancing it, rather than depending on it for your happiness.
D. You're not your status in the community. You're a worthwhile person for existing.
All of that is what you should focus on to not be so outcome dependent, and thats what I would suggest focusing on right now. There's also the legitamte question of how to have more of an impact on your chosen field, but I think that would require more ifnromation.
