Be proud that you trade.
Be proud than you own the choices you make.
Be proud that if you succeed it it's your doing and that if you don't that you had the courage to know that it was in your hands.
Here is a quote that might inspire you to be proud of who you are and to stop trying to appease those that don't get it with easier explanations.
The Trader
"The symbol of all relationships among such men, the moral symbol of respect for human beings, is the trader. We, who live by values, not by loot, are traders, both in manner and spirit. A trader is a man who earns what he gets and does not give or take the undeserved. A trader does not ask to be paid for his failure, he does not ask to be loved for his flaws. A trader does not squander his body as fodder, or his soul as alms. Just as he does not give his work except in trade for material values, so he does not give the values of his spirit -- his love, his friendship, his esteem â except in payment and in trade for human virtue, in payment for his own selfish pleasure, which he receives from men he can respect. The mystic parasites who have, throughout the ages, reviled the trader and held him in contempt, while honoring beggars and looters, have known the secret motive of their sneers: a trader is an entity they dread - a man of justice."
--Ayn Rand
