I have some good advice for your work. If you can do the following things, you will succeed in doing everything.
Firstly, whatever you do, you must be punctual and hard-working. If you sow a good seed, you will get a good harvest. If the seed is in poor quality, the harvest will also be very bad. And if you sow nothing, you will get nothing at all. Nothing.
Secondly, you must be honest. As honesty is the moral tuition that everyone should have. If you treat other people friendly and sincerely, others will also respect you.
Thirdly, you must be tolerant to others, since no one is perfect in the world. Everyone has his own faults, but if you can see everything on other person's perspective, there will be no problem at all.
What's more, when you are in a big company, you should not only respect the leaders, but also get on well with the colleagues. Sometimes, you should try to please your boss, so that you could have more chances to be promoted.
Last but not the least, don't ignore the little things, because such a little thing will have a great effect on your life. So you should start yourselves at the bottom, in order to get enough working experience. As you have enough working experience, nothing you will be afraid.
