WHEN AM I “ALLOWED” TO QUIT AND NOT BE LABELED A QUITTER?

Summary from the TLDR Founders newsletter

Startups that don't grow significantly within two years of dedicated effort, fail to secure full-time commitment or seed funding, or reach $1 million in Annual Recurring Revenue (ARR) after four years, should consider these as milestones to reassess their viability. These time frames provide a reasonable period to evaluate if the venture warrants continuation or if it's time to move on.
