But for me, what I like about the dividend way is that there is no thinking involved - I collect all the dividends for a year, and that's all the money I have for the following year. Easy. Never going to run out and as I am only 40, this could go on for a while. At the worst I might have to cut back spending or even find a part time job - but should be ok. But certainly do not have to worry if my capital will last - which would be a big worry for me. Also never have to worry about when/what shares to sell because guaranteed I will sell at the wrong time.. 
It's true, I've read and understand so much about the 4% rule, but I'm always drawn to the dividend way of living. If I stopped work now and cashed in my holdings and bought something like the Dividend aristocrats, I'd cover all my living costs on their divi alone.
If it wasn't for the capital gains I'd have to pay I'd probably start doing this now and finally get out of the foord equity unit trust I first bought. It has been performing reasonably well, but the divvies are low, and the costs are higher than I'd like.
I could keep my STXIND there for growth, as I have sideline income to cover the remainder of my costs without needing to sell.
Whenever I have a bad day at work I keep asking myself why I'm still at the office...
