This is my 13 post. So I’ve decided to make some digression. Usually number 13 is considered as unhappy. It seems not a rule for me. This year 13 is my happy number. On 13th January I’ve signed new job contract. It was just about 13:15 (or might be it was exactly at 13:13). What is more interesting, sum of digits in that date (13-01-2006) is equal to 13 (1+3+0+1+2+0+0+6=13). Number of building I’m now working in is also 13. As for now I’m quite happy in my new job.
Also according to Walter Schneider 13 is definitely happy number. I’ve observed that for me the unhappiest day in month is 26th. In fact it is 2*13. When I use Walters method to it gives me: 26 => 40 (2*2+6*6) => 16 => 37 => 58 => 89 => 145 => 42 => 20 => 4. So 26 is unhappy number and it confirms my observations :).
