I can now sleep, having found the word which desrcibes me:
desultory (DES-uhl-tor-ee) adjective:
1. Marked by absence of a plan; disconnected; jumping from one thing to another.
2. Digressing from the main subject; random.
[From Latin desultorius (leaping, pertaining to a circus rider who jumps from one horse to another), from desilire (to leap down), from salire (to jump). Other words derived from the same Latin root (salire) are sally, somersault, insult, result, saute, salient, and our recent friend, saltant.]
