My best pension plan was not to have kids.
Now 53 mortgage paid off, quit work, living off savings until the pension kicks in - if I'd worked another 5 years it would be a full pension worth another 200 a month - but I reason that amount ain't worth the reduction in my life expectency.
All the people I know who spent years saying how wonderful kids are and how I'm missing out now hate me. lol
Finances are wonderfully easy when you eliminate unpredictable and random factors such as dependents.
I'll be dead long before retirement age
I'm planning to do all I can to mess things up for the generations that follow. That's my retirement plan.
