いたい！Thorns!

「朿」は表外漢字です。それは「thorn」を意味します。I see it as a plant 木 with hooks on it:  thorns.So we have:

策, policy/plan:  Write out with your bamboo (stylus) your plans to clear the thorns.  Or maybe:
                           Write out your plans to catch the golden fleece on a thorn bush.
刺, pierce/thorn:  A thorn is like a knife on a thorn bush, piercing you.
