Becoming assertive , takes a lot of practice. I took an amazing course in 2014. That explains assertiveness it is about stating your needs without overriding others and being aggressive. The phrase is pick your battles, there times that assertive may not worth it like little annoying harmful habits . Other times , assertiveness is absolutely necessary. This eight week course sent me on, a major change that always refreshing myself on. Remember assertive is not aggression it’s asserting your needs, rights with out overriding others rights. The best example is a friend ignoring a simple request of removing her shoes in her house, you ask her twice and we still hasn’t take them off. Then you need to tell her that either you respect my rules or leave and don’t visit until she does. That is saying this is not okay and telling her how to treat you. People will respect you more the assertive you are .
