Rather than forcing oneself to stick to a fixed duration with a countdown timer, it would be more beneficial and motivating to use a stopwatch, allowing one's practice to adjust naturally to their internal state at the moment.

This debate illustrates a tension between two approaches to discipline: intuitive flexibility and rigid structure. Behavioral psychology research, particularly on self-regulation, suggests that motivation is often boosted by autonomy (Self-Determination Theory, Ryan & Deci), which validates the stopwatch approach for certain profiles. Conversely, for individuals with attention difficulties, the use of timers acts as a structuring external framework that helps maintain engagement, a finding frequently observed in studies on mindfulness-based interventions (meta-analysis by Vinkers et al., 2020). The idea that resistance to a timer is an opportunity for observation is a classic concept in contemplative psychology, but there is a lack of direct clinical evidence to claim that one method is superior to the other. The risk of turning practice into a performance competition (wanting to go 'longer') is a documented pitfall in the gamification of habits. In short, the community is deeply divided, with votes showing that each method meets very personal cognitive functioning needs.
