In 58 years of Berkshire management,most of my capital-allocation decisions have been no better than so-so. In some cases, also, bad moves by me have been rescued by very large doses of luck. (Remember our escapes from near-disasters at USAir and Salomon? I certainly do.)Our satisfactory results have been the product of about a dozen truly good decisions – that would be about one every five years – and a sometimes-forgotten advantage that favors long-term investors such as Berkshire.
所以，不要想着靠分散多买发财，要想尽办法把握少数真正的好公司的买入机会。当然在A股这有点难，过去白酒低估时我还不懂炒股，近几年自己真正可能经历的就是2023年初因为来水不好、增发收购资产的不确定而跌到20左右的$长江电力(SH600900)$
