bullet-riddled advice

My blog will not be in the fancy "paragraph" format that seems to be so desirable. What can I say? Time just keeps disappearing on me. The last two times I tried to post, blogger said "No." Granted those attempts were a week apart, but that's not the point. The point is that there are a few things I think new tutors should know. Because I am a late poster, most of these things have already been mentioned, but I will still state them as though they are fresh and tasty:

• It's ok to tell a student when the session has stopped being productive. You don't have to let anyone waste your time.
• You will use the reference books a lot. Don't try to pretend like you know every answer. Most students can sniff out a fake.
• The people you are working with are like-minded, awesome folks. Don't be so serious that you can't have fun with them. They will also teach you a lot.
• A drink of water is a handy accessory while on shift.
• You will encounter students who are much smarter than you are. This doesn't mean you can't help them. On the flip side, you will also be faced with morons and you'll have to pretend you don't notice.
• The schedule is not as iron-clad as it seems.
• Droning on about grammar rules is not a good idea. Students don't care. If something is a problem, show the student how to fix it, but don't spend five minutes explaining that/which if it has only come up once in the paper.
• Use links to explain yourself when responding to online submissions.
