Tracking your own life (one thought a day)

Today I found a cool diary from a store and I decided to buy it. It's not a usual diary; basically you just write down a few words a day for five years. Each date of five different years is put on the same page so you can easily compare what happens to you across years.
Before this, I have actually kept a diary book for so long and I still find it very interesting to read my old entries. By reading I can remember how I was years ago and laugh or smile at the ups and downs I'd been through. That way I can be grateful more for the life I have! However, I wrote it rather irregularly (not everyday) because of the busy activities I got.
With this new diary, I think it is easier to write everyday because it's not a whole page; it's just as little as one sentence to remind me of my own memories. I started writing on it today and I hope I can still commit for the next five years. We'll see.
