1. Stay calm.
Keep your cool and remind yourself that they are just people trying to take you off your path. You have goals and ambitions, you have a mission. Don't let them take you astray.
People tend to put pressure on you with their behavior but that shouldn't bother you at all. However, you should know that if you have a hand in their actions, you will have to sort the issue with them.
2. Do not take physical action.
I know at times it can get tempting but do not let your emotions take over your decision making skills. You will end up getting into trouble one way or the other once you've done the damage.
You have to be extremely careful. Control yourself under pressure.
If you do end up smacking someone across the face, make sure you apologize before any further action is taken against you.
3. Keep distance.
Learn how to keep distance when needed. Keeping distance will not only rid you of their actions, it will make them realize that what they are doing is wrong.
Be warned that keeping distance too much may lead you into thinking that everyone is ignoring you yet you're the one distancing yourself too much.
Keep distance but to a limit.
4. Don't take anyone's crap.
Of course, annoying people will make you angry. Use the anger wisely. Let them know that what they are doing is wrong. Being harsh at times is the only option to set someone straight.
Clearly tell them to stop what they are doing or if you'd like, to back off.
