Books by Diego Segura

Everything in Excess Is Good.
What if extraordinary results come from excess, not restraint?

You Are Not a Failure: From Failure to Unlimited Success.
Every setback can become a stepping stone.

I Want to Start a Business, but I Don't Know How: Find Your Idea and Launch Your Business.
The roadmap from a spark of an idea to a launched business.

I Want to Start a Business but I Don't Have Money: Get Paid Before You Spend a Cent.
You have organised your ambition around an exception.

I Want to Start a Business but I Can't Quit My Job: Test It Before You Quit.
The job you cannot quit is the cheapest test equipment you will ever own.

I Want to Start a Business but I'm a Coward: Find Out Which Fears Are Telling the Truth.
If reason agrees with your fear, running is not cowardice. It is arithmetic.

I Want to Start a Business but I Never Actually Start: Preparing Is Not Progress.
Preparing feels almost exactly like progress. That is the trap.
About My Philosophy
Every book I write starts the same way: I read everything published on the subject, then report what it actually says, including the parts nobody wants to hear. As a result, these are the ideas that survived.
Do it in excess.
Moderation is a fine rule for dessert, but it is a poor rule for the things you want to build. So give the work you care about more focus, more hours and more intensity than feels reasonable.
From Everything in Excess Is Good 02Failure is an event, not an identity.
A company can fail, and a launch can fail. However, you are not a failure, because every setback is information you did not have yesterday.
From You Are Not a Failure 03Start before you know how.
Nobody knows how the first time. So find your why, test the idea cheaply, and learn the rest while you move.
From I Want to Start a Business, but I Don't Know How 04Get paid before you spend.
Money is rarely the thing missing. In addition, a paying customer proves more than any funding round.
From I Want to Start a Business but I Don't Have Money 05Test before you jump.
Keep the salary and run the experiment, because the job you cannot quit is your cheapest laboratory.
From I Want to Start a Business but I Can't Quit My Job 06Check the fear against the evidence.
Fear is not the enemy. It is a claim, and claims can be checked. Some of your fears are telling the truth, so find out which.
From I Want to Start a Business but I'm a Coward 07Preparing is not progress.
Progress is the moment a stranger can answer you. Everything before that, however careful, is rehearsal.
