It means you take things personally. It can be negative or positive, depending on the context. It can mean, positively, that you are a feeling and caring person. But often times people use it negatively to try to justify hurting your feelings.  

Answer 2

"Take this to heart" means:

"Please take this seriously but not offensively"
