Cure Excusitis
Treat excuses as symptoms of a small premise. Diagnose them, then prescribe one specific action.
David J. Schwartz · 1959 · Success Psychology Special
A field guide for enlarging the room inside your head
The Magic
of Thinking Big
A mid-century motivational classic with one clean thesis: the size of your belief sets the size of your behavior, and behavior quietly edits the size of your life.
The Thesis
Your life grows to the size of your working assumption.
Schwartz writes like an editor of personal possibility. He is not asking for fantasy. He is asking you to notice the tiny, respectable sentences that shrink your behavior before the world ever gets a chance to respond.
The book keeps returning to a practical loop: upgrade the belief, create evidence with action, choose larger environments, and refuse the disease of good excuses. Thinking big is a discipline, not a mood.
That makes the book feel part success manual, part newsroom. Every day arrives with a headline. The question is whether you let fear write it or whether you edit it into a larger assignment.
02
Build Confidence
Confidence follows controlled exposure: speak, ask, lead, and collect proof that you can survive visibility.
03
Upgrade the Room
Spend more time around standards, conversations, and expectations that normalize the larger life.

Action Steps
This Week, Enlarge the Assignment
Vote on the move that would make your current life negotiate with a bigger premise.
01
Rewrite one shrinking sentence
Catch one thought that starts with 'I can't,' 'not yet,' or 'people like me do not.' Rewrite it as a larger working assumption and act from that version for one day.
I'll do this
02
Make the bigger ask
Choose one request you have been downsizing: a meeting, role, rate, deadline, introduction, or responsibility. Ask clearly before you negotiate against yourself.
I'll do this
03
Create visible evidence
Ship one small proof point this week: a proposal, prototype, note, pitch, page, or conversation that makes the bigger future observable.
I'll do this
04
Audit your rooms
List the five people, feeds, or places shaping your standards. Replace one low-ceiling input with a room that expects more precise ambition.
I'll do this
05
Run a seven-day confidence experiment
For seven days, do one action that makes you slightly more visible. Track the result as evidence, not as a verdict on your identity.

"Believe it can be done. When you believe something can be done, really believe, your mind will find the ways to do it."
