How can I improve my work ethic? I think it's a little whack. I want to enhance it and make it stronger. Any ideas? What motivates you?

Working well will give you pride in a job well done and isn't really that much harder. Engaging yourself in your work also passes time quicker. Slacking off is a form of theft from your employer, they expect a little but overdoing it will make you feel like a thief. You will also learn more and be promoted if you do your job well.

Even when you volunteer you should take pride in your work. If working for a charity or even helping your mom build a fence you should do your best for your own sense of worth. That is why you are asking you don't want to feel like a slacker.

Don't work to please your boss.

Work hard, so you can feel good that you're trying your best and getting stuff done.
