If you can buy the best companies, over time the pricing takes care of itself.

Trying to prioritize among things we're unlikely to do is pretty fruitless.

It's in the nature of stock markets to go way down from time to time. There's no system to avoid bad markets. You can't do it unless you try to time the market, which is a seriously dumb thing to do. Conservative investing with steady savings without expecting miracles is the way to go.

A great business at a fair price is superior to a fair business at a great price.

A few major opportunities, clearly recognizable as such, will usually come to one who continuously searches and waits, with a curious mind, loving diagnosis involving multiple variables. And then all that is required is a willingness to bet heavily when the odds are extremely favorable, using resources available as a result of prudence and patience in the past.

Let me know what your problem is, and I will try to make it more difficult for you.

If you have competence, you pretty much know its boundaries already. To ask the question (of whether you are past the boundary) is to answer it.
