Language learning deserves special mention. It is, bar none, the best thing you can do to hone clear thinking. Quite aside from the fact that it is impossible to understand a culture without understanding its language, acquiring a new language makes you aware of your own language: your own thoughts. The benefits of becoming fluent in a foreign tongue are as underestimated as the difficulty is overestimated. Thousands of theoretical linguists will disagree, but I know from research and personal experimentation with more than a dozen languages that (1) adults can learn languages much faster than children83 when constant 9–5 work is removed and that (2) it is possible to become conversationally fluent in any language in six months or less. At four hours per day, six months can be whittled down to less than three months.
