I am sure that most everyone can understand the feeling of wanting to make everyone around them happy. It's a stressful job to ensure that every person is getting the same great experience you want them to have. It's time-consuming. And it's just straight up hard. And to be honest, almost impossible. Scratch that, it is impossible. There is going to be a day when you wake up and realize that you have been battling for a useless fight of putting a smile on the face of the person next to you.
I have always had the idea of keeping the peace and staying away from conflict. Conflict makes my stomach churn and I panic. Questions run through my head and I try to think of what course of action I need to take to patch up the situation. It wasn't until recently that I discovered I was causing myself more stress than it was worth. Sure, making people happy is something you should work towards, but it's not like a pass/fail kind of grade. Things are not going to be perfect. So what if someone is not completely satisfied with the situation. that's where communication skills come into play.
Talk it out. Just because your BFF Jill doesn't come into the situation happy, doesn't mean that she won't change her mind or look at the facts in a different light. And it's not like you aren't going to be friends at the end of the day because she thought you should have brought chocolate chip cookies instead of raisin. Maybe you love raisin cookies and you deserve to treat yourself too.
Don't lose yourself in the situation. Don't lose sight of your well being or happiness trying to bend over backward to please some else. There are going to be different opinions out there and you need to remember to respect them to the best of your abilities. Stay away from having a one track mind, but don't forget that what you believe is totally acceptable.
You won't be able to please everyone. So take a step back from the situation and don't stress yourself out. Don't let other people get under your skin and make you want to take them to war.
