Some days feel heavy long before anything difficult actually happens. You wake up fine, but by mid‑afternoon, even small choices feel oddly exhausting. What to eat. What to answer. What to ignore. Nothing is technically hard, yet everything feels harder.
That feeling has a name, but more importantly, it has patterns. Decision fatigue isn’t dramatic or obvious. It shows up quietly, disguised as procrastination, irritation, or the urge to avoid choices altogether.
