47 is a prime number, and the sum of its digits is also a prime. 47 is a good annual Goodreads goal because it’s one less than a number divisible by 12. Let’s call these Goodreads Primes:

11, 23, 47, 59, 71, 83, 107, 131, 167, 179, 191, 227, 239, 251, 263, 311...

I think Douglas Adams made a mistake when picking 42 as the answer to everything. 47 would’ve been a better candidate because of how prime it is.

In any case, 47th Happy Birthday to me 😀
