Look at yourself first not everyone else.

Measure yourself in how successful you are instead of only focusing on everyone else. This doesn't solve anything nor help anyone including yourself. Push yourself everyday and set goals to see how much you can do.

Even if you don't like the job where you are at, do your best. Even when your boss doesn't treat you well. The customers will see the kind of person you are just by your actions. You will shine above because you have chosen to be your best. By doing this, it will open more doors of opportunity to serve more.
