First of all, here are Jude Claybourne's Reason's To Be Grateful - an ace example of listing happy things. She's on Day 120. And there are puppies wearing coats.
Second, read some Letters of Note. Who doesn't love a letter? Incidentally, sending and receiving actual mail from friends and other people you don't hate (note to my bank: go away, I don't want a loan, a mortgage or to pay back my overdraft)is one of the nicest things there is. Write a couple of words on a post card and send it to a friend. They'll like it, I promise (as long as the words are not 'hello, I secretly hate you'). Also, writing complaint letters is fun because sometimes you get free stuff. Another 'cheer up for cheap' tip for you there. Yell and be rewarded. Possibly.
Second to last-ly, here is a nice blog about tattoos, if you are in to that sort of thing.
And lastly, I typed 'design your own shoes' into Google and these are the web sites that came up:-
Create your own Chuck Taylors
Vans custom shoes
Milk & Honey Shoebuilder (this one's just for girls, or guys with fetishes)
Customise your own Timberland boat shoes! Who wouldn't want to do this??
Hours of free fun. Unless you click 'buy'. I take no responsibility for making you do that (PS buy me some shoes)
