I saw this on a post from Brent Ozar recently. It's a post of pictures from his company's vacation last year. There are two sentences. The first is that you should listen to a PSA that notes your company gives you vacation for a reason. However it's the ending line that stood out to me:
Remember who you really work for. Schedule your 2015 vacations now.
Who do you work for? You work for yourself, and you should remember that. By yourself, I mean you, personally, and your family. That's who you should put first and take care of, ultimately.
Employers come and go. Remember that and insist that you get your vacation time. Even if you want to sit in your house and stare at the wall, take the time.
Have I scheduled mine 2015? Not completely, but I did schedule a week with my son at Seabase for a Boy Scout trip. I'm also waiting to hear from my brother before we plan a larger family vacation. And, of course, I'm taking a few days in Jan and Feb to ski.
I haven't always used all my vacation each year, however I also get a lot of vacation by US standards. 25 days, so I often sell back a few to the company. However I have made sure I've used my vacation the last couple years and taken 20 days off.
Life is short. You work for you. Work on your career, but remember to take care of yourself (and your family).
