15 years ago, I would have given anything to be able to work PT, have more time with my kids and for myself, but it just wasn't an option financially.
15 years on and I am so thankful. 3 promotions later, I earn well and enjoy the luxury of not having to worry about budgets, can buy what I want within reason. More importantly, I get to plan to retire early with a good income.
At 30 ish, it's easy to assume that working at 60 is fine and not much different. For many, it becomes much much more difficult and tiring but you are still young enough to be able to do a lot outside of work and have fun. Not everyone is in bad health. Being able to make the most of it from 55 or even 60 is fantastic.
As for the children? Well mine grew up to be very kind (they always were), hard working, ambitious and resilient. They are happy, healthy and emotionally well adjusted.
Do I have any regrets? Hell no! I'm counting the years to retirement with great plans afterwards that I'll be able to afford. I can't imagine having to work until 67 and then only have enough to pay my bills and have just very limited disposable income for the occasional treat.
