Two different sports, one lesson
Handball rewards quick decisions under pressure. Shot-put rewards repeatable technique and patient accumulation. Both punish inconsistency more than they reward occasional brilliance.
Parallels with research work
- Fundamentals first: Data cleaning, baselines, and evaluation splits are the warm-up nobody skips.
- Honest measurement: A personal best only matters with proper conditions—same idea as held-out geographic splits.
- Adjust without ego: Bad training days and failed experiments are information, not identity.
What I still practice
Show up on schedule, log the session, review what worked, and change one variable at a time. That rhythm transferred directly from sport to long ML projects.
