&quot;Timeboxing&quot;.<p>It <i>can</i> be effective.<p>The challenges for me:<p>1. Boxing sufficiently large chunks of time that I can actually <i>work</i> on a project. Task-switching has immense costs.<p>2. Actually having a path forward. If I&#x27;ve yet to find a good way to tackle a problem, or worse, if I&#x27;m stymied <i>by having been mislead as to a possible pathway</i> (a false Bayesian prior, or similar concepts in logic&#x2F;truth), it can be quite frustrating.
