So, I've done the math dozens of times, and my logical self knows that I am fully able to successfully retire, at least from a a financial standpoint. My wife is on board with my decision....this is something that we have both talked about and been working towards for years. Every time I look at the numbers, I keep thinking that if I just stay another 18 months, I will earn another year and half of salary, my pension will increase by x%, etc. I know I don't need the extra money, and it will really not have a material impact on my lifestyle, but, man, I feel like I am almost doing something wrong by leaving money on the table. No doubt if I stayed, I would probably feel the same way in 18 months---if I just stay another year, I can have an even bigger pension. Kind of like a rat on a spinning wheel, never able to get off.
Are you assumptions conservative? Try out different scenarios .. if it makes sense .. why not make the jump?
Also .. can you make some extra money using your expertise?
