You can always pick out insecure people, by listening to how many backhanded compliments and subtle insults they hand out. The people who try and act like they have it all together are usually the biggest messes!!
I love this. I strive every single day to achieve these things. It isn't always easy. The last one is the most difficult because most of us would like the care we give to be reciprocated, but more times than not it isn't. Often times we feel taken for granted and that is the feeling I strive to suppress.
