For more than two decades, I've prepared tax returns and managed investments for many of the same families. The people who had done everything right kept describing the same feeling: "I know I should feel okay. I don't." The gap was almost always structural. Their investments and their taxes were being treated as two separate problems instead of one.
That observation became my book, The Tax-Smart Retirement Paycheck. It lays out a three-stage income framework that separates near-term income from market swings and accounts for taxes from the first dollar. For two days only, the Kindle edition is 99¢. https://www.amazon.com/dp/B0HNHF33FL
