1. Always be Learning.
Should you leave a job for money? A promotion? Maybe. But the number one way you know it's time to go is when you feel like you've stopped learning new things."
2. Get experience.
Work part-time, do internships, volunteer, etc., in the field you want to work in while you are in college (and even high school). I did that and it made me realize I didn't want to go to architecture school, a Friend of my mine did that and she was never turned down for a job in her field partly because of her impressive college internships.
3. Work hard.
My grandmother told me that 'if you want to put your hand out on payday, you have to do the work.' Being successful means having a good work ethic, doing your job.
4.Learn other people's jobs.
Don't just learn your job. Know yours inside and out, then learn what those down the hall do. First, you'll know who to go to when you need help. Second, the more skills and institutional knowledge you pick up, the more valuable you are to the company. I've gotten a lot of opportunities because I've gotten comfortable with development side of things, too."
5.There's no such thing as a perfect job.
"Even the coolest, most glamorous jobs in the world have bad parts, and you just have to deal with it, because that paperwork or those early mornings or that one awful co-worker lets you spend an awful lot of time doing something you love. Deal with it."
6. Don't burn your bridges.
Your professional network is extremely valuable. No matter what your reason is for leaving a job, never burn the bridge when you move on ... I've seen people basically 'tell off' a boss as they go out the door. Even if what you tell them is true, and you never want to work for this company again, you gain nothing by airing all your grievances on the way out. You never know where you may run into these colleagues again in the future!"
Make sure your desk is always neat before you go home. That's not easy for someone who isn't neat at heart, but people walk by your desk in an office all the time. They make judgments based on what they see. If you look neat and organized, you'll make a better impression. it's important to be organized and efficient, and to make a good impression to every client."
