To cultivate sustained focus, practice the 'Single-Task Sprint' method. Identify the single most important task for a given period. Before you begin, define a clear, small win for this sprint (e.g., 'complete the first draft of the introduction,' 'analyze 3 data points,' 'outline section A'). Set a timer for 25-40 minutes (adjust based on your current attention span, starting smaller is fine). During this time, eliminate *all* distractions: close unnecessary browser tabs, put your phone on airplane mode, silence desktop notifications. Commit to working *exclusively* on your chosen task until the timer signals the end. When the timer rings, immediately step away for a deliberate 5-minute 'reset break' – stand up, stretch, look out a window, or take a few deep breaths. Avoid checking emails, social media, or starting new mental input during this break. This trains your brain to engage deeply and then fully disengage. Repeat this cycle throughout your workday for maximum benefit.
