Learning Japanese

I'm trying to come up with a sort of Ten Commandments for Learning Japanese, but I can't reach to number ten. What I've got so far is this:

1. Thou shalt not use keigo.
2. Thou shalt start with kanji.
3. Thou shalt not translate literally, not even close to it.
4. Thou shalt write and speak and write again in Japanese only, using kanji (typing is OK, don't pay attention to strokes and stuff like that, just get the message through).
5. Thou shalt not expect people to laugh at your jokes as told in Japanese.
6. Thou shalt not think that by knowing おいしい、寒い、暑い、そうですね、そうですか、すごい、you know any Japanese.
7. ...
8. ...
9. ...
10. Thou shalt not use keigo, not if you haven't at least passed JLPT N1 with a 100% score on all sections, if you are not 110% sure what you're doing, or if you don't want to get embarrassed - stick to the ーます form, which covers a huge range of situations.
