I think the Buddhists would disagree with you on the moral valence of this.
There's plenty of Western philosophy as well that sees "not caring" (at least not about things outside your own actions) as very desirable. Not to mention the Epicureans, for whom freedom from worries ("ataraxia") was the highest attainable state.
OP's fear of (being seen to be) "coasting" would be entirely foreign to them.
