There are going to be times in your career when the musicians surrounding you are either much better or much less skilled than you. How you conduct yourself around both types of peers says a lot about you as a person.
Feeling like you're constantly struggling to keep up with the skill level of the people around you can be emotionally taxing if you allow it to be. Instead, watch your peers closely and notice with they do differently than you. Who do they study with, and what's their practice routine like? Be humble enough to ask them for advice if you're stuck with something you know they can do well. Most importantly, don't try to trip them up or bring them down. That kind of behavior only reflects poorly on you.
On the other hand, it's easy to get cocky or patronizing when you're the principal of your section, but there's no call to be that kind of person. Be kind to the people you lead and assist them whenever you can. Show them tips or tricks as the opportunities present themselves; you helping your peers improve only makes the ensemble sound better. Don't try to keep others down so that you can kick back and stop working hard to be the best. Be generous with your knowledge.
Whether you're at the top, the bottom, or somewhere in the middle, it all comes down to being a good human being.
