I'm a Pessimist

If you stay with a pessimist then you will become a pessimist too. If you stay with someone who like saying, "We can do it. We can try it. There are many roads to Rome." then you will become an optimist. With which one I am standing now then? Unfortunately, the first one. Sometimes, it's hard to fight, I even become a pessimist too gradually. No passion, no spirit. Sigh...
