Drifting. A drifter. Aimless. Meandering. Going with the flow. Blowing in the wind.
This is a state that one may find oneself in at times. Or permanently.
Not unlike floundering in its incarnation drifting is quite different.
A drifter moves without purpose, without a goal, without compunction to a degree.
A drifter can be like any person really, so ethics and integrity are present to the extent they are present in anyone. The idea of no compunction would mean not dictated by a specific objective.
Drifting aimlessly toward nothing looking forward to nothing being nothing.
