Fiona - "for" and "to" are called prepositions in English grammar. There are many prepositions in the English language - maybe about 60 or 70. Here are the meanings of the two prepositons that you asked about: For 1. Duration of time: We walked for two hours. 2. Distance: I walked for five kilometers. 3. Purpose: I bought this jacket for you / We should meet for lunch 4. In the direction of: She left for New York. (to go to New York) 5. In favor of: We are for the proposal. We are cheering for the Chinese team. 6. Considering: The boy is clever for his age. (considering how young the boy is) It is too early for me. [this is meaning number 6] For example: Five AM is too early for me to wake up or to go to work. (this means that it is too early for 'somebody like me' to wake up or go to work) The taxi driver will ask you to pay 100 RMB for driving you (for somebody = for him) (meaning number 3) You should always do something nice for your mother. (for somebody) (meaning number 3) To 1. In the direction of: Turn to the right. 2. Destination: I am going to Beijing. 3. Until: from Monday to Friday / five minutes to ten 4. Compared with: They prefer basketball to football 5. With indirect object: Please give it to me. 6. As part of infinitive: I like to ski / he wants to help. 7. In order to do something: We went to the store to buy soap. what's the difference of "to sb"and "for sb" You must give 100 RMB to the taxi driver (pay to somebody) (meaning number 5) You should always be nice to your mother (your mother = somebody) (meaning number 5) I hope my answer helps you...

to answer the first question: "It is to early for me." is the better way and is what people (at least in the US) will say. I don't know if "it's to early TO... me/whoever" is that wrong technically, but I don't think I've heard anyone say it.
