Can bad thoughts influence our actions ...?

I do think that bad thoughts can lead to bad actions. Perhaps not in very case, but at least in some cases I do think that it does. I think that sometimes it's just part of human nature and we just can't help it.

yups thought changes our action,i have read somewhere that thoughts can move mountains. you can test it on your own,first think some negative thoughts and then tell your friend to test your strength by pushing your arm down,now just be relax think of the most recent victory you had and then tell your friend to test your strength again.your friend can feel the difference you must had more strength when you were feeling more positive thoughts
