Get used to people disliking you. If you are a person, you have an opinion. If you have an opinion, someone disagrees with you. Heck, some people disagree with you without even knowing you or your opinion.

Who cares? Having an opinion means you care about something. If people dislike you for caring about something, what does it matter to them?

Once you get over the fact that people will dislike you, you feel free to do whatever you want. Free from external opinions that can have an extraordinary effect on your effort, and hence your outcomes.

So, get used to people disliking you. Just don't make them hate you.
