There are 78 permanent SPECIAL points in Fallout 4.

• You start off with 28 points.
• You can find a You're SPECIAL! book in your Sanctuary home for another point.
  • Can only increase a maxed stat if a debuff like alcohol is used to temporarily lower one of your maxed stats
• You can train all your SPECIAL stats up to 10, so that's 42 remaining points.
• Additional Bobbleheads (for each specific SPECIAL stat) can be found, 7 points.

You can max out your character with 10 in each SPECIAL trait provided every time you level up you simply choose the appropriate training to increase your stats (as opposed to choosing perks).

Remember, there's no level cap, so you can keep on levelling and start getting other perks later.

So you start off with 28, but you can easily improve all of them to 70, should you choose to only train those perks starting at Level 2.

This means 70 - 28 = 42. Meaning the earliest you could max out all your stats is getting to Level 43, while every time you level up putting points in the stat you want to increase, provided you also don't find any bobbleheads along your way.

Additionally, some perks grant permanent increases in stats at specific times of the day or at a certain HP level, so those are technically also "permanent".

As discussed here - in order to assign a worker to a resource you must be in workshop mode and then approach the person you want to be the worker, speak to them and "command" them:

...then go to the location you want them to work and you'll have the option to assign them to that post.

They'll then walk over from their original position and start working.

The person icon will go red again if you reassign a person who was already assigned to another task, or that person is currently not performing that task (ie: sleeping). Unfortunately, there is no method of seeing an overview of all tasks your settlers are currently assigned to, however you can see what each individual is assigned to if you have visibility of that individual and their assigned task - this picture will show you what I mean:

This settler is only assigned to half of these carrots, another settler is doing the others, so when I target this settler is highlights half of the carrots.
