（抱歉迟到了，我有几个交货期...)

以后，after a given time, hereafter

Guardian:
所以以后，我希望你能注意安全 (Shen Wei: So hereafter, I hope you will be able to take care. To which Zhao Yunlan responds with 谢谢关心, thank you for your concern, lol.)
你以后就不用在害怕了 (Zhang Ruonan to Wang Yike: you won't need to be frightened any more, *sniff*)
那好，从今天以后我的名字就叫做沈...巍。(Okay, from today on the name I am called will be Shen...Wei.)

My practice:
你能不能快点，我三点以后一定要再出去。
下周以后，我打算每天都弹钢琴。（真的吗呀）

(Oh yeah, I asked 瑜姐 about 我在上海工作 vs 我住在上海。 Her first reaction was the typical native-speaker "Huh? Oh yeah, I guess it does work that way. 很奇怪，为什么呀," but she suggested it might have to do with single-character verbs--you would say 住在 or 睡在 or 坐在, but not 吃饭在 or 工作在 and so on. Another data point?)

Practice:

以後别再提他。
我们以后要小心一点。

she suggested it might have to do with single-character verbs

Oh, interesting. 睡 doesn't seem as definitely "locational" as the other ones, so maybe it really is just a matter of single-character verbs having separate rules, like the separate rules undeadrobins was describing for single vs. multi-character verbs + 得...

你说的对呀：）

Single- versus multiple-character verbs is certainly a fairly easy principle to grasp, if nothing else!
