Try these regularly for two months:
1. Take half an hour of exercise three times a week (Not sure I ever manage this one!)
2.Count your blessings, at the end of each day, reflect on at least five things you are grateful for.
3.Have an hour-long, uninterrupted, conversation with your partner or closest friends each week. (Nothing like cake and a good chat!)
4.Plant something: even if it's in a window box or pot. Keep it alive!(Hmmmm..)
5.Cut your TV viewing by half (It didn't mention blogging!)
6.Smile at and say hello to a stranger at least once a day (I like this one)
7.Make contact with at least one friend or relation you have not been in contact with for a while and arrange to meet.
8.Have a good laugh at least once a day (If all else fails you could try tickling yourself, though really in all honesty, it doesn't work well!)
9.Give yourself a treat every day. Take time to really enjoy this (Chocolate!)
10.Do an extra good turn for someone each day.
Do you have anything to add?
