Step one:
Before you go and send an angry email to anybody, you need to sit back and count to ten. That doesn't mean that you can't write the email, you just want to delete it as soon as it has been written. If you send an angry email, it might make you feel better in a matter of seconds, but the person who receives the email will remember it for a long time. If you make them mad, most likely they will do what they can to get you back for that hurtful email, possibly without you even being aware of it.

Step two:
Go out of your way to talk to people, including others in the workplace. Even if you do not have in depth conversations with the people, you can still be polite and friendly to everybody that you meet. Having a smile or a kind word can make somebody else's day. In addition to talking to people, you also need to respect people and show respect, even if their behaviors or habits annoy you.

Step three:
Your mother probably taught you that when you were little that you needed to treat people how you wanted to be treated, this is still true when you are an adult. You want to treat your friends the way that you want to be treated. If you are mean and rude to your friends they are not, going to want to continue being friends with you, but if, you are nice and helpful you will make even more friends and keep the ones that you currently have. Even you despise somebody you should still treat them with dignity because it reflects better on you. People will remember you for the good things that you have done, rather than your rude or degrading behavior.

Step four:
If a subject does not concern you, do everything that you can to prevent being involved in the matter. People will try to lure you in and get you to take sides if they are having a problem with somebody, but if it does not affect your directly you need to stay out of it. You also need to watch out for people who are going to manipulate you into getting involved, do not fall for their tricks; if you do, you can end up alienating a close friend and turning many more into enemies.

Step five:
Never gossip about your friends. Even if you are not the one spreading the rumors or talking about your friends listening to the gossip is just as bad. If people begin talking about your friends in front of you, you have two choices: you can walk away from your "friends" or you can tell your friends that you are not comfortable talking about this subject and ask them to change the subject. Something else that you want to avoid is making false allegations about anybody, especially friends. Before you accuse somebody of something, you will want to talk to that person to see if it is true. Do not listen to the gossip of other people about what others might have done. By not gossiping and not making false accusations you can follow the rule of causing no harm, which will help you avoid making enemies out of your friends.
