Even though Ron Conway is highly regarded, in my humble

opinion, his philosophy of encouraging timely exits undervalues the power of perseverance, as demonstrated by Elon's rescue of Tesla from near bankruptcy, Jobs’ revival of a struggling Apple, and Jensen Huang's near death experience of acquisition threats, which led to transformative breakthroughs. Angel investors, despite their expertise, are often limited by their vision, constrained by heavily focusing on measurable benchmarks and short-term metrics.

After all, it's 謀事在人 成事在天, this applies to both founders and angels.
