Alas, I sold my entire GEICO position in 1952 for $15,259, primarily to switch into Western Insurance Securities. This act of infidelity can partially be excused by the fact that Western was selling for slightly more than one times its current earnings, a p/e ratio that for some reason caught my eye. But in the next 20 years, the GEICO stock I sold grew in value to about $1.3 million, which taught me a lesson about the inadvisability of selling a stake in an identifiably-wonderful company.

可惜的是，在1952年我以15，259美元的价钱将全部的GEICO股份出清，然后将所得资金投入到西方保险证券公司之上，这项变心的举动，一部份的原因是因为西方保险证券当时的股价相当吸引人，本益比只有一倍左右，然而在往后的二十年间，当时被我卖的的GEICO股份的价值却成长到1，300万美元，这样的结局让我体会到绝对不能卖掉一家明显的好公司的原则。

The production process needs only 3 hours , but the yield of Tencel fiber raises about six times compared with that of common rayon. The NMMO solvent is completely innocuousness to human bodyand can be completely recovered (about 99.5%) and reused. So the production process is green process. Tencel fiber is credited green fiber in the twenty-first centuries.

相比普通粘胶纤维，整个生产过程仅需约3小时，然而Tencel纤维产量可提高6倍左右；Tencel生产中所使用的氧化胺溶剂对人体完全无害，并可完全回收(99.5%以上)和反复使用，生产中原料浆粕所含的纤维素分子不起化学变化，无废弃物排出厂外，不会污染环境，属于"绿色生产工艺"，所以Tencel纤维被誉为二十一世纪绿色纤维。
