I don't pay to much attention to how I might withdraw money from my IRA or my wife's Roth IRA and her traditional IRA or my 401k Profit Sharing plan, beyond the mandatory RMD's for each. Unless the company is sold, I'll draw my existing salary until I die. Our children will probably receive the retirement accounts as rollover inherited IRA's and 401K, assuming the politicians haven't destroyed our economy and rewrite the tax laws....who really knows?
If you work hard and have a skill set to match success and wealth is yours for the taking
