What Hugh Jarse said x1000!
And what ever you do, don't be a ******. You need to decide whether you are the type of person who can fly the line day after day, by the book and not "feel the need for speed". If showing off your skills to your fellow pilots makes you feel cool, don't be an airline pilot.
By all means be proud of your achievements, and revel in your ability to improve, but don't sit there thinking you are all that, it will come across a baseless arrogance. The guys and girls I respect the most are those with great gobs of humility, ability comes with time and will be respected without any advertising by you.
Welcome aboard!!
