💪 劲头 = 劲 (strength) + 头 (head) — the strength in your head, your drive
劲 carries the sense of force or energy; 头 means head but here acts as a noun-suffix turning it into a thing: the vigor or zeal you bring to a task. Think of it as the get-up-and-go that pushes a job forward.
头 — 页 (head/page) + 豆 (bean, phonetic)
The traditional form 頭 combines 頁 (xié), meaning 'head', with 豆 (dòu) as the phonetic component. 頁 itself originally depicted a person with an emphasized head. The simplified form 头 is a modern shorthand that replaces 豆+頁 with a simpler shape while keeping the same meaning of 'head' or 'top'.
