I was always taught to work your butt off for everything you get, if you work hard usually it comes to you, sometimes it won't but that doesn't mean give up and roll over
Work your butt off
Working hard shows for me the first day you start, we can see it by the way you go from place to place, how you complete tasks, how you interact with other people, slackers usually hang out with slackers so when we fins a start usually he is surrounded by other stars and they are a great source of inspiration and other employees.
The people I and we do not get along with are those that skate by each day doing only enough to keep under the radar and not be noticed, but with our company, we track everything so that shows very quick unless another motivated worker simply calls and tell us "this guy is no good"
Work for it
I do think working hard can be taught but must be done early in life, we are not normally going to take someone who slacks and turn them into a superstar so when we're looking for potential painters we are looking at past jobs, how they present themselves, do they stand up and shake hands when someone walks into a room.
We want to be surrounded by awesome people, people who lift us up and bring something to the table and that goes for customers too, if your complaining and grumpy each day we do not need to work for you or be around, we can move on to ones that lift us up and will be awesome clients who bring
other awesome clients.
