"Researchers found that individuals who tend to procrastinate often do so because they fear not meeting their high standards or worry too much about failing. The study also showed that this fear of failure and the habit of overgeneralizing failures (like thinking one mistake means you're a failure) strongly connect perfectionism to procrastination." — Mark Travers, Forbes, 28 May 2025

We won't put off telling you about the origins of procrastinate: it comes from the Latin prefix pro-, meaning "forward," and crastinus, meaning "of tomorrow." To procrastinate is to work or move slowly so as to fall behind; it implies blameworthy delay especially through laziness or apathy. English has other words with similar meanings, such as defer and postpone, but none places the blame so directly on the person responsible for choosing a later time to do something. Procrastinate is also a malleable word: English speakers have wasted no time creating clever variations, most of them delightfully self-explanatory. Don't let coinages like procrastibake, procrastinetflix, and procrasticlean pass you by; they may not meet our criteria for entry into the dictionary, but their potentials for use are undeniable.
