We use 'like' as a preposition before a noun or pronoun, and it means 'similar to'. He ran like the wind. Not: He ran as the wind. We use 'like', and not 'as', to compare appearances. This house looks like a castle. 'As' can be used as a preposition. It means 'in the role of'. Dan, as your friend I have to say you're not a good singer. We often use 'as' to talk about people's jobs. I work as an actor. Be careful using 'like' and 'as' because the meaning can change: 'As your brother, I'll try to help you' means 'I actually am your brother'. Change it to 'like', and it means 'I'm not your brother but I want to act in a similar way'.
