Relationships are a fundamental part of life. No matter what you want to achieve, it is much easier when you have other people who can help and support you along the way. Toxic people treat you badly and give you the wrong idea about what you should expect from relationships. Toxic people take more of your time than good people because they cause more problems and are just hard to deal with. While you will certainly have to deal with toxic people in your life; from my experience, you can quite often just cut them out of your life. The reason you can do this so easily is because while toxic people are more demanding; they offer very little, if any, value to your life.
