3000 years old and still relevant

This is a follow-up to my post Ancient Texts #1: Instructions of Šhuruppak . Below is a list of "instructions" I found to still be relevant today:

9-20 You should not vouch for someone: that man will have a hold on you; and you yourself, you should not let somebody vouch for you (1 ms. adds:: that man will despise (?) you).

2-27 You should not loiter about where there is a quarrel; you should not let the quarrel make you a witness. You should not let (?) yourself ...... in a quarrel. You should not cause a quarrel; ....... ...... the gate of the palace ....... Stand aside from a quarrel, ...... you should not take (?) another road.

35-38 You should not pick a quarrel; you should not disgrace yourself. You should not ...... lies; ....... You should not boast; then your words will be trusted. You should not deliberate for too long (?); you cannot bear ...... glances.

42-43 You should not speak improperly; later it will lay a trap for you.

65-66 The eyes of the slanderer always move around as shiftily as a spindle. You should never remain in his presence; his intentions (?) should not be allowed to have an effect (?) on you.

126 You should not pass judgment when you drink beer.

170-171 Fate is a wet bank; it can make one slip.

175-176 You should not work using only your eyes; you will not multiply your possessions using only your mouth.

177 The negligent one ruins (?) his family.

202-203 A loving heart maintains a family; a hateful heart destroys a family.
