What I do is have One person for cooking, One person for medical and One person for building, If you didn't notice that there was no hunter your right! I don't have a hunter until mid-game, this is because of growing (Later in chapters!) if you have One really good builder that means he/she builds better quality things. If the product/Furniture is better quality means better comfort. Better comfort means better mood boosts (also important)
Special Needs
The worst part. Be sure to check the medical tab for addictions. IF a good character has an addiction to a drug, specifically Luciferium is bad. (https://rimworldwiki.com/wiki/Drugs) An addiction can be bad: Symptoms can include: breakouts, Sickness, Death and more... If the Drug is not Luciferium, you should be able to get over it. If the character has a scar, said scar will induce pain. If the said scar is on a leg, you could well... chop it off... 0________0
