There's been a lot of talk lately about work-life balance, work-life blend, or work-life integration. Heck, some even change it to life-work and think it changes everything. I can't say I've ever believed in work-life balance.
I don't have work friends and life friends, I just have friends. I don't have designated work time and play time, I just have my 24 hours to manage. I don't have work-life balance, I have work-life blend -- and I couldn't be happier.
