And I thought I was doing so well... having a cold and two small children whilst trying to stick to the plan of being nice? Not a great idea... although to be fair to them I think that I may have been a bit generous to myself thinking I had made it through the first two days.
Although I hadn't been unfair, I have to admit that saying something factual can also be classed as not being nice - not necessarily mean or horrible, but not really nice in the strictest sense of the word.
However, having now read most of The Happiness Project I have realised that trying to achieve perfection regarding being nice for 2 whole weeks is a pretty tough challenge for anyone (apart from those people who are born that way...).
I will be re-attempting this task again in the future (working from home today and being allowed to say things to my computer about various emails I received during the day made me feel a lot better), but will define better what my measure is going to be as I realise that it is not always possible to be nice constantly.
Time to rethink this particular challenge...
