Some people can be toxic and they can suck the life out of you with their negativity, selfishness, complaints and co-dependency.
While you need relationships, you do not need every single one. It is better to surround yourself with positive people, rather than negative ones. You shouldn’t have to sacrifice your sanity in order to please others.
Don’t let your own kindness control you. You can still be a good person without having to be selfless. And you definitely don’t need selfish people to determine your kindness.
In 2015, minimize and remove negative influences from your life. It is understandable that you cannot avoid toxic people, but try to minimize your contact with them. Make the choice to surround yourself with positive and supportive people as much as you can.
