Mashable.com run an article on the above subject recently. They are not industry-specific but applicable across the industry whether you are in the finance, IT, engineering or media. I suppose the examples given are by people who had already been in the working world for a while and they had been proven useful over time.
I would like to add two more principles that I think are particularly helpful from my observation.
Be credible – people like to deal with people that are reliable. Be the “go-to” person. Build your reputation based on that. You might have skills or talent but if you lack credibility, no one wants to have anything to do with you in the long run.
Be helpful – this seems to be so easy but trust me, some people underestimated the power of lending a hand to help someone who is in need. “I owe you one, mate” – you would not know the meaning or power of your act until you desperately needed a favor yourself. But if you do not start sowing when you can, you won’t be able to reap it in the future.
