The old tips and tricks thread has retired, it was fairly outdated at this point too.
So here's a advanced brand spanking new one.
Tip numero uno: When you start a new game, go to the market and buy ropes, weapons and armor for you and your starter slave. Next go back to the mansion, equip the equipment, and if you haven't already, transfer the ropes to the travel bag.
This way you have a fighting chance to survive your first encounter and can catch some new slaves!
#2. Agility is a very good first investment in stats. It raises awareness, which in turn stops you getting ambushed while out in the world.
