Whenever cats are mentioned in conversation, there is always reference to their independent natures. They are their own "people" and they are sufficient unto themselves. In all her books Brene Brown is very definite in asserting "I am enough" - and my cats would certainly agree with her!
It's taken me a long time to learn this lesson - I always felt that I was not "enough" or I was "too much", but now I'm reaching a place of "enough-ness" where my self-esteem is finally catching up with the person I pretended to be.
Putting on a front of self-confidence is not the same as having an innate sense of your own worthiness. It's all well and good to 'fake it until you make it' but at some stage you have to put it into practice and start believing in yourself and what you have to offer. To have enough self-worth to not have to lean on others all the time and to know your own value without having to be propped up by friends is when you truly start living life.
Being able to be alone with yourself, to like yourself, to know your own value - these are traits cats own instinctively and they are worth investing time in developing. Believing in yourself and acknowledging your own worth is just the beginning - from there you can start to branch out and encourage others to be their very best too, and who knows where it could go from there?
