Many here are much closer to the end than the beginning, with the risk of running out of time, before magic can work.
Many here additionally because having adhered to that advice already "won the game", resulting in the possibility of losing what was won having far higher priority than before.
In both cases not to be invested at times can be the most rational decision (contrary to one born out of fear), resulting from weighing all factors, not only the beauty of LTBH, but also age, living expenses, income, assets etc.

More, more, more has never been a motivating factor for me. At 19 I set a goal of early retirement and we accomplished that option, even if DH found he lacked the desire to follow through and at 66 is still doing some consulting. At least he no longer puts in 60-80 hours a week and is certainly healthier for it. My investing style was pretty aggressive, being 100% stocks beyond the 3-6 months expenses in liquid funds. In 2016 the investing world became too confusing and unpredictable for me, and I quite simply stopped putting more cash into the market. Timing was appropriate, given our retirement goals and we are now about 50% non-equities. I have absolutely left a ton of cash on the table and am completely OK with that. I sleep well at night and we have plenty of funds to do what we want as well as to help our kids get a leg up in their adulting. They should receive a decent inheritance, though their college education and planned gifting along the way is all we have told them to expect. I have no desire to impose a couple of trustafarians on this world.

The ability to be content is a great tool in building an asset base, in terms of having seed money via LBYM. It's also a great way to hold on to what you have. Greed and fear are both emotions that have no place in investing.
