This is so true on many levels. If you are walking along and expect the negative that is exactly what you will get! If you are walking in a negative state of mind it makes it that much easier to miss good opportunities that you would have seen if you were in a good mood.
People will scown at you if you have a scowl on your face. If you have a smile on your face the other person will smile as well. It’s contagious! Like attracts like!
Of course, if you are in a panic thinking I must think good thoughts all of the time! You won’t be attracting good, instead, you will be attracting insecurity and more panic. If you are thinking good thoughts and expect things to come to you then you are telling the universe ‘give me something’ and the universe will reply back ‘give me something’. If you have good thoughts and ask the universe ‘how can I help’ the universe will reply, ‘how can I help you?’
That is the danger of overthinking things.
