I really don't like a lot of people and prefer to be at home away from all the crazies. Everyone else seems to be so good at "getting along" in meetings or during team work. Some people I don't even notice in a group setting. I always feel like I have to take the lead or nothing will get done. But when I take the lead or act decisively, I feel overbearing. Are others better at "getting along"? Please add comments!

If you can't say nothing nice.
Do you fake how you act around other people?
Cool ver.
Do you fake how you behave around other people?
At work you need to be professional so feelings cannot influence your behaviour too much. Leadership comes naturally for some and providing you know when to be a leader (and not take over) and when to be quiet, then thats fine.
So yeah, try it on, see what you can do. It's a great skill to have when you are forced to get along with someone you don't particularly like ;)
