It's simple and doesn't involve guessing what the market will do. Just as Browne recommended, you pick a percentage to hold for each asset, and rebalance on a fixed schedule that's long enough to avoid short-term tax rates. If percentages aren't off by much, don't bother.

It's not gambling, and it's not original with Browne. The percentages aren't magic, they're just anything that has worked reasonably well historically over many different economic conditions. Most fee-based financial advisors will give you a strategy like this. It's probably the most widely-accepted strategy in finance.
