Early-stage founders' ignorance of future challenges can be a benefit. It allows for bold, quick action without the caution that experience might bring. This "fail forward" mentality builds momentum and resilience that might otherwise be stifled by fear of the unknown.

For entrepreneur Emma Hernan, the fear of failure is less significant than the regret of procrastination. She advises aspiring founders that the greatest risk isn't that a venture might fail, but that it might never start. The opportunity cost of waiting is higher than the cost of a potential misstep.

The essence of the entrepreneurial journey is the ability to tolerate immense uncertainty and fear over long periods. It involves working for months or years with little visible progress, making high-stakes decisions with limited information, and shouldering the responsibility for others' livelihoods. This psychological endurance is the ultimate differentiator.

Waiting to overcome fear before pursuing new ventures is a recipe for stagnation. Pushing beyond your comfort zone is naturally terrifying, but it's also exhilarating and essential for growth. The key is to act in spite of the fear, because that is when you are most alive and your potential expands.

Founders shouldn't be deterred by their lack of knowledge. Seeing the full scope of future challenges can be overwhelming. A degree of ignorance allows entrepreneurs to focus on immediate problems and maintain the momentum crucial for survival in the early stages.

Do not wait to feel confident before you start a new venture. Confidence isn't something you find; it's something you build through the repetitive act of showing up and doing the work, even when you're terrified. It is a result of consistent courage, not a cause of it.

The number one reason founders fail is not a lack of competence but a crisis of confidence that leads to hesitation. They see what needs to be done but delay, bogged down by excuses. In a fast-moving environment, a smart decision made too late is no longer a smart decision.

The motivation to start a company wasn't about a guaranteed outcome but about embracing the ultimate test of one's capabilities. The realization that most founders, regardless of experience, are figuring it out as they go is empowering. It reframes the founder journey from a path for experts to a challenge for the determined.

Tubulus co-founders decided to launch their company after a single successful experiment, driven by passion rather than a thorough market analysis. This 'healthy naivety' helped them push forward despite industry skepticism towards their antibody-drug conjugate (ADC) technology at the time, which was considered a difficult area.
