I agree about the value of setting up DDs for charitable giving.
I also think it's a good principle to give something from your money at the start of the month and see it as being like a DD for your electricity bill or whatever, rather than just a whim or something that's left over. It can become a habit - a good one.
We give to several charities and look to give around 10% of gross income. When you think about it, that amounts to several thousand per year. It is something we have always done...starting when our incomes were low in our 20s and continuing as our incomes have risen. We chose to cut back in other areas if times were tight, rather than not to give. I think it's a mindset and the exact percentage is less important than being in a mindset if giving and not just thinking of what you have as your own.
Personally, I only give to charities that deal with people rather than animals, but that's a personal choice.
I don't like the street chuggers who try to sign you up, but it clearly works or they wouldn't be doing it. I also don't really like the door to door collectors. Recently, one looked really shocked when I said i didn't want to give ÂŁ2 for a local children's charity, and then said something like 'are you sure you don't want to help local children'. I pointed out quite politely but firmly that such a comment wasn't appropriate - that trying to guilt-trip people is wrong and rude and they don't know anybody's personal circumstances or even what they might already be giving to charity. I wasn't rude at all about it, but I thought it was an important point to make, plus that collector was doing a disservice to all collectors....people simply won't open the door if they behave like that.
But, don't let the things that annoy you like the bombarding emails or pushy collectors stop you finding a way to give that works for you. Most of us are so fortunate, even when we feel unfortunate and giving something makes a difference and also gives us a sense of it not being all about us.
