Carrying a bad attitude is like having spoiled milk on your mustache. Pretty much everywhere you go, you'll claim that the place stinks really bad.
You struggled to find where does the smell come from, when it's there right under your nose. Life is all about your attitude towards something. We can't control our fate, but we can control our reaction towards it.
A proactive person sees challenges as opportunity, while a reactive person sees challenges as the end of the world.
Just like the story of two shoe salesmen who were sent to an Island to sell shoes. When the 1st one saw everybody there walking with bare feet, he sent a message to the HQ saying, "Will return tomorrow. Nobody here wears shoes."
But the 2nd salesman, who was facing the same exact situation, sent a telegram to the HQ saying, "Please send me 10,000 shoes. Everybody here needs them."
It's your attitude, not your aptitude, that determines your altitude.
