Stay focused on the positive things in your life. Your attitude affects how you present yourself. A positive attitude just makes you look better. Check out our blog post on this - http://career-dragon.blogspot.com/2013/01/a-positive-attitude.html
Life is not about escaping trials, but about how you choose to respond to them. It boils down to two choices: run away and ignore it or face it head on. Changing people and things around you won't fix the problem, it's merely a Band-Aid. Truly fixing something requires you to address the root, not just the fruit. When you change yourself (starting with your attitude - the outer reflects the inner), everyone and everything around you changes in response to you.
