Sorry for the short hiatus, been down with a bad flu and had lots on my mind the last few weeks....
How many times have you celebrated your birthday at work? Doing your job, getting stressed, sometimes getting acknowledged it is your birthday, and sometimes not?
I learnt many years ago that it is better not to work on your birthday as it is a day for you to celebrate how you want, with who you want. A day for yourself to relax and ponder of the past year and what you have done.
So, just take a day off when it is your birthday. Relax and enjoy yourself instead of stressing on work.
