hi,
Basic quality my dear, is to have right attitude.
As a fresher, learn.
Be focused on your work, goals, targets and so on.
Aviod office politics.
Respect all, from your boss to the lowest rung.
Offer help, before being asked.
Stretch your time and stretch your work.
Spend considerable time in reading on the area you work.
Smile at everyone and exchange pleasentaries.
Be flexible and also firm.
Dont stick to cribbers. Beware of them.
Add on more formal part time courses to help you in your job.
well, the list goes on. But remember, It is up to you to choose success by a simple rule of changing oneself rather than changing the world.
All the best.
regrads,
DK
