Actually, if you're using those for shipping--which is the only thing about Prime I'm interested in given how much I distrust and dislike Amazon--I accidentally discovered an even easier way to exploit them.
If you add something to your cart, then go to check out, you can accept the free Prime period, select Prime shipping, then remove the free Prime trial from your shopping cart before you pay and it will just...keep the Prime shipping on the order.
The first time I did this I was convinced I had fucked something up because I went to cancel my free trial after the item I bought had been delivered and instead of having the option to cancel I was given the option to start another free trial. The second time it happened is when I caught on that I was on to something, and I then tested it again and it just...worked. I'm sure they'll fix it eventually, andit's probably totally useless if you like other parts of Prime, but if you want free 1- or 2-day shipping on an order, well then this worked for me as of my last order about two weeks ago.
I had gotten out of the habit of reading for pleasure after college because I felt incredibly burned out on it. That had started to bother me because I used to read as one of my main hobbies, so last year I set the goal of reading 1 book. I did that, and read a couple others.
This year I set a goal of 5 books and was able to do that by March, but then I ended up with about 9 in flight books and wasn't making much progress with them. I felt like I had them hanging over my head and it was stressing me out, so I'm now working on the goal of finishing them by the end of the month.
Its been really nice to realize that I still do love reading and that I still can finish a book even with all the stuff going on in life, its just a matter of sitting down and reading. I credit a silly goal with helping me remember that.
