Should founders commit early to one big idea they believe in, or pivot quickly toward whatever gains traction?

Paul Graham · published Apr 2006

Stubbornness is a disastrous quality in a startup; founders need determination combined with flexibility, always moving but improvising around obstacles.

Like a successful running back, who runs around or spins out of obstacles and will even briefly go the wrong direction, but never stands still.

The stick-to-your-vision approach is wrong for startups; founders should not get attached to the original plan because it is probably wrong.

Startups are more like science than like winning an Olympic medal — the problem isn't well-defined, and most successful startups end up doing something different than intended.

Paul Graham · published Feb 2009

In startups, unlike fields such as mathematics, sheer persistence is usually enough to succeed provided you keep morphing your idea.

Some people could never become good mathematicians no matter how long they persisted, but startups aren't like that.

A startup idea should be treated as a hypothesis rather than a blueprint, because determination without flexibility is a greedy algorithm that leads only to a mediocre local maximum.

A determined founder risks following a long, hard path that leads nowhere; you need to push forward while twisting and turning to find the most promising path.

The determination founders need must be paired with flexibility about goals, not the 'never give up on your dreams' kind that fixes the original plan.

The world of startups is so unpredictable that founders need to be able to modify their dreams on the fly, like a running back who goes sideways or backwards to get downfield.

Founders' first instinct should be to find a big idea they fundamentally believe in and would double down on for years, rather than pivoting between ideas until something gets traction

Startups are about taking big risks; hopping ideas weekly until one gets a thousand retweets is taking no risk at all, just looking to make a quick buck

Pivoting is like divorce: one or two is reasonable, but doing it repeatedly suggests the problem is you

Abandoning the current space and moving to a different one would be no problem for the team, for him, or for the investors, because the mandate is to figure something out rather than to pursue one fixed idea

They raised enough to explore, and the commitment is to the exploration, not the initial space

The biggest cause of bad startup ideas is the 'still life effect': taking the first idea that comes to mind and then feeling, at each stage, that too much time has been invested to change it.

Big projects grow out of small ones, so sunk time accumulates before anyone reconsiders — as in spending a month painting a still life set up in four minutes.

source Sunk cost attachment not genuine conviction drives founders to stick with bad first ideas

Paul Graham · published Apr 2005

The fix for the still life effect is not to stop plunging into ideas but to consciously discount sunk time and re-ask whether the idea is what people will pay most for.

An idea gets woven into your thoughts, so attachment is much stronger than for something simple like a name, which is already hard to change.

The test of whether idea-switching is healthy is whether the ideas form a progression that reuses prior work, and whether users are excited by the new direction.

If you can re-use most of what you built you're probably converging; restarting from scratch each time is a bad sign; and users' excitement is external evidence.

source Idea switching is healthy when it reuses prior work and users are excited not when restarting from scratch

Paul Graham · published Jun 2021

Abandoning an entire type of work is much harder than abandoning a single project, and the more determined you are the harder it gets, because determination itself tells you to try harder instead.

Like a Spanish Flu victim fighting their own immune system, determination turns against you: instead of giving up you conclude you should just try harder, and there's no clear way to say you're wrong.

source High determination paradoxically makes abandoning a whole type of work harder since determination argues for trying harder not quitting

People badly underestimate how hard it is to judge startup ideas, especially their own, which is why the advice to change your idea is hard to follow.

Experienced founders learn to keep an open mind after discovering how bad they were at telling good ideas from bad.

You can never reliably predict which startup ideas will work, so the right approach is to do whatever seems best at each point.

Even YC itself is an unproven hypothesis that its founders can't yet judge.
