What makes a good job?
Interest. When you are doing something interesting for you, you'll enjoy your work and get a chance of great achievement.
Ability. Ability comes from your knowledge and diligent practice. More ability, higher position.
Teamwork spirit. You couldn't achieve a great course only by yourself. You have to co-operate with other people and good teamwork-spirit makes you get well along with others.
Attitude. Always be positive, optimistic, and encouraging. People like to co-work and follow a person with these qualities.
All in all, a good job is not from what you do, but who you are.
