Impulsive

When the party stops to discuss what to do next, to strategize, to meander, etc. set a timer for X minutes (as predetermined with your DM). If no action has been taken or decision has been reached when the timer runs out, roll a d4,

1. You manage to stay put a little longer (set the timer again, but decrease the time by half).
2. You decide to take direct action without alerting your party (approach and initiate combat/conversation, start walking straight forwards, start swimming across the river, etc.)
3. You alert the other party members that they better settle on what to do now, because you're not waiting any longer. (Within a minute, your character must have taken an action by either following one of the proposals made by the other party-members, or by acting on an original idea.)
4. You decide to take direct action, but inform your party members before wandering off.
