You don't really need heavy investment in intelligence early on. You can get by just fine repairing your stone axe and eating charred meat and boiled water. You don't get much, and those points can be valuable for a particular build.
There are three critical things starting off:
1. Prioritize what you need, and stick with it. Do you need materials to build? Focus on it. Do you need to work for the trader to get some early tools and antibiotics? Focus on it. Do you need to scavenge? Stick with it. Avoid becoming too distracted with everything in front of you. Have a dump chest and save 'inventory sorting' activities for nighttime. Getting distracted often means picking up too much loot, which inevitably leads to overencumbrance, which wastes daylight. Pick up only what you need, and avoid sidetracks or aimless waffling.
2. Prioritize who you want to be. Spreading your perk points thin may help early on, but it can sabotage obtaining higher tier perks. EVERYTHING looks important, but what you don't realize is that you CAN do without them by compensating elsewhere. Why cook when you can earn dukes to buy pasta from all those random vending machines? Why get Boom Headshot if you want to be a stealthy-boi when you can focus heavily in Hidden Strike, Shadows, and Ninja Movement? Do you want to be a builder, a melee tank, a ninja looter, a run-and-gunner? Focus on the key skill combinations that fits your build first.
3. Always have a way out. If you hear an angry zombie and you don't know where it is, back out. If it's BM night, have an accessible plan B location if your defense plan fails or isn't done. If you focused on priorities, you should be ready.
