I hit on an idea the other day I'm pretty excited about. Because I haven't actually worked out the cash flow logistics of it, I cannot say if it is viable.
The idea is staying with working 3 days a week once the mortgages are done but take 1 week off each month. This is in contrast with what I was thinking of doing, which is work 2 days a week the entire month.
Preliminary thoughts show a potential of enough income to fund the week off which would likely end up being a travel week somewhere. Whereas, if I were to take a week off while working 2 days a week, the budgeting gets tighter (6 working day month vs. 9).
I'm intrigued enough with the idea to think it through further. It looks like it will fall somewhere in between where I am currently and where I am planning to go.
