Congratulations on having the self-discipline and good fortune to put yourself in that position. You have been blessed. Does the $2M of investments include your 401k and pension lump sum or will you take the pension as a monthly annuity? Are you single or do you have a partner with investments and/or retirement income? How much will it cost to maintain the standard of living you desire in retirement? If you are a frugal mid-westerner who can survive on $80k a year or less, then you're golden. If your lifestyle requires more than that, you may need a more detailed financial plan. I detest CFPs that charge 1% or more of assets annually, but you can find someone to help you put together a plan that you're comfortable with for a one-time fee and you should be just fine.
There are no shortage of companies paying 3-4% dividends right now. 5% or more if you're willing to take on more risk. 10 year treasuries are just shy of 4%. I have other 5 to 8 year bonds paying 5-6%. You can get 4.4-4.5% on 5 year FDIC insured CDs right now if you're risk intolerant. So you can easily bring in $80k or more in interest and dividends per year without touching the principle or taking any capital gains. 5 year or longer maturity bonds and CDs can help you get to Medicare eligibility at age 65 and then you can start taking social security whenever you want/need it.
Then there's the whole question of what you will do with your free time? Hobbies, volunteering, join a service club, etc. You need to stay busy with something for your own physical and mental health.
Good Luck with your retirement!
