You can't please everybody.
Every one of us is born unique in our ways, outlook, attitudes, likes, dislikes, opinions, and perspective. Come to think of it, even if we have a lot of things that are different from each other, we still are set by boundaries, norms and principles for socially acceptable behavior so that we can co-exist peacefully.

Here are just basic things to remember. One is to realize and put in our hearts that we should respect other's ways, outlooks, attitudes, likes and dislikes, opinions or perspective. If we do that, there comes the acceptance that no one has to be like you or you don't need to be like the others, just so you could get along.

Do not expect others to see your way. If they don't, respect that. Do not expect others to make the same decisions that you do. If they don't, respect that. Conflicts are second-nature to humans. People are argumentative to a fault, in many aspects of our lives. We just have to stop and listen. We don't have to agree, but respect others ideas and opinions.

If you don't want to get stumped while expressing your thoughts, then don't do that to others as well. In this generation and age, people are accustomed to just being in a group, organization, or having friends that also have the same viewpoints as we do. By doing this, we limit our capabilities to inculcate respect.

And remember, you can only be on the same wavelength with someone else to a minimal extent. Even twins are not so much alike.

Next time you would have a cross (a disagreement) with someone, remember all these. You are at an advantage because that person might go on because he doesn't know that respect is needed to ensure that we live peacefully. And if you stoop down to his level, you are the loser, not him. Understanding is respecting. Respecting is not a way to please everyone but a course to ensure that you are a principled person.
