It's common knowledge that we should be careful with what we put into our mouths, but did you know that you should also be careful with what comes out?
For instance, I once heard or read somewhere that if you tell someone not to forget something, their brain will immediately register the word 'forget', perhaps causing them to forget! Instead it is recommended that you tell them to remember to do whatever it is that you wish to remind them. I'm not sure if this is true, but it makes sense, doesn't it?
And someone once told me to rephrase what I tell myself. I was talking to them about what I was studying, and I said 'I have to get this essay finished tonight.' This person replied, 'Well, don't put too much pressure on yourself. Instead of saying that you have to, try saying that you want to. This way if you don't get it all done tonight you won't be so down on yourself.' He also went on to say that you could use this for anything. Instead of 'needing' to make a phone call, you would 'like' to. Rather than saying 'I should have' say 'I could have' and so on.
After this conversation I had a good think about the way in which I phrase things and how simply by rewording what I say I could feel a whole lot better about myself.
So watch what you eat, and watch what you say, and if both of these are done right you'll have a good day!
