If you spend the whole day at the fish market, even if you haven't touched a fish, you'll leave with a fishy smell on you; but if you spend a day at a perfume shop, even if you haven't bought anything, you'll leave smelling wonderful. Your environment always leaves a mark on you. Being around people who love to complain, you'll find negativity everywhere; being around people who always make excuses, you'll find it hard to change. But if you associate with proactive people, you'll be inspired to move forward; if you spend time with grateful people, you'll see that beauty is everywhere in life. The "scent" of your environment will ultimately stay with you forever.
