Well, this photograph is not only about instant gratification. It's also about the value of good things.
This is my second pair of Red Wing 2233 boots, which I bought 14 years ago in 1996, and which are my weekend boots for general mayhem and destruction (I have a pair from 2003 which I use during the week). This is the part about the value of good things - sometimes it's cheaper to buy more expensive but excellent things, as long as you take just a bit of time every now and then to take good care of them.
Which brings me to the title and the question of instant gratification - the boot on the right was exactly like the boot on the left before I spent ten minutes caring for it with lots and lots of shoe polish, and a good brush. Ten short minutes to go from a wreck to something absolutely stunning. This feeling of instant personal realization is priceless for our self worth, considering that we have jobs where the time scales between starting something and seeing (or not) the fruits of that labor can be measured in weeks, months, or even years.
That's why it's great to have a few things in life that are this quick and fulfilling.
