Caring too much can be harmful... (I concur with this and don't regret caring)
"Caring can be a good thing because it shows you are sensitive to what is happening around you. The key, however, is to care with moderation, i.e. to recognise the “too much” and know it is harmful. This is easy to say, but hard to do. Be mindful of it though and try to practice where possible."
