Most ICT packing problems are not about forgetting something dramatic.
They come from smaller mistakes:
The easiest fix is to pack for the first day properly and let that remove the obvious friction.
Make-up pay sounds straightforward until real employment arrangements get involved.
If you are salaried, you want to know whether the figure is correct. If you do shift work or variable pay, you worry about whether the amount reflects reality. If you are self-employed, freelance, platform-based, or between jobs, the process can feel much blurrier than the simple summary people repeat.
The useful way to understand make-up pay is not as one neat rule. It is as a few common pathways depending on how you earn.
Your first ICT after ORD does not usually feel hard because the military side is mysterious. It feels hard because civilian life is now mixed into the equation.
You are juggling work, family plans, missing gear, unread notifications, and the suspicion that your No. 4 may no longer fit the way it used to. That is why the first ICT often feels harder in the build-up than it looks on paper.
The easiest fix is to stop treating it like one big problem and handle it as a short prep window with clear categories.
