I am reading a bit most days of A Year To Clear by Stephanie Bennet Vogt and finding it often chimes with what I am thinking about or doing. (Although that could be, as with horoscopes, just because most of what she talks about is relevant to most people much of the time!)
I've been paying attention to my instincts lately and found what she has to say about 'inner knowing' quite interesting. She also calls it intuition or sixth sense and says this about deciding whether or not to do something...
If it feels right do it.
If it doesn't feel right don't do it.
If you don't know wait until you know.
You can decide not to decide.
