The world conspires to prevent action. Humans (like all lifeforms) are naturally lazy. We want to get the biggest benefit for the least expenditure of energy. There's always a voice in the back of our minds saying, "nah, don't bother doing that--it's too much work and it's not worth it."
Everything we see reinforces this voice. When we see hustle culture, we think, "that's cringe--I would never want to do that." And so we don't. When a startup fails, we think, "see, it's not worth it." And when a startup succeeds, we think, "well, they got lucky, and anyway they had rich parents, so they were bound to succeed."
Worse, it's easy to do things that feel like action but are really just time-wasters. Reading one more advice post. Organizing our workspace. Learning one more tool/technology/process.
Moving faster means don't wait. Act now.
"But I don't want to move fast and break things!" That's the voice again, preventing you from acting. Yes, moving too fast absolutely has risks, but not as many risks as moving too slow.
The only guarantee in life is that we'll be dead one day, and I for one want to get as much out of my limited time as I can. I'm not going to waste it waiting.
