25 before 25

When I realized that I have only one year left until my 25th birthday, I decided I better make some serious goals to commemorate my quarter of a century!
I have been working on this little book for a few weeks. I still need to think of ten more goals, and find a way to bind the book. I didn't want to rush my goals. The first 15 came easy, but now I'm a little stuck. A quarter of a century is important!
I am trying to find a good balance between silly or fun goals and more strenuous ones. Also, when you think of your goals in a certain time frame it makes you realize how short a year really is.
I plan to have this finished by my birthday, so I have just under a month!

Any binding ideas for me?
