独自一人───be on one's own;发现───find

seated on a wooden chair under a parasol in the open air, talking with newly-acquainted friends about one's own trivial life over a cup of tea, is probably a pleasure, too.───坐在户外撑着遮阳伞的木椅上，和新认识的朋友一边喝茶，一边谈着自己小小的生活，或许也是一种惬意。

city, as Aristotle understands, will always exist in a world with other cities or other states, based on different principles that might be hostile to one's own.───城市，如亚里士多德所认为，将永远会,和其它城市或国家同时存在，根于不同的管理原则,可能还会对自己人怀有敌意。

well and good to jump off the deep end if no one's depending on your earnings. But if you have a family or other dependents, you have to be absolutely sure before you strike out on your own.───如果没人靠你的收入生活，能跳出困境当然好，但是，如果你有家庭或其他依赖你的人，那你就必须在自主创业之前绝对有把握。

Uh be on one's own also has many disadvantages, right?
