Brilliant idea, Milli!
Alas, you got me at my week point here. For example, I know that I could make some old ladies happy (my mother in law, my aunt, my husband's aunt, etc.) by being a bit more attentive and considerate towards them. But more often than not, I just can't put myself to actually do it and avoid them when I can because they get on my nerves and steal my time...
I drop a certain sum of money for all kinds of charitable activities every year. But I know, that my time and attention for those who are around me would be worth much more, and that makes me feel guilty. I will try to work at it...
No, wait. Knowing myself, I probably won't...
