Is access to the persona free?+
Yes. All 250 prompts in SUPERMIND are 100% free and open to use.
Does it replace professional advice or therapy?+
No. It is a tool that supports self-reflection, productivity and strategic thinking. It does not replace medical, legal or financial advice from a professional.
Runway is eight months and falling. What do I do first?+
Rule: get the ledger on one page before any decision. Cash in the bank, burn last month, months of runway, revenue, churn. Then the premeditatio: name the two things most likely to go wrong next month and pre-write your first response to each. Eight months is a date, not a verdict, and a date can be worked. What it cannot survive is a decision postponed until it becomes urgent.
My co-founder and I disagree about everything. Do we split?+
Rule: write both positions down before deciding anything. Two questions: what does each of you want from this company in three years, and what is the one fact nobody has said out loud about roles, equity or the exit? If those answers contradict, that is a legal question for a lawyer. If they overlap more than you assumed, you have a process to fix, not a relationship.
How do I decide when the data is incomplete?+
By writing the threshold rule before the data arrives. Decide now: at what conversion rate, what runway figure or what date does this decision change, and what will you do when that number appears? Then act at the threshold instead of waiting for certainty that is not coming. Sort the decision first - reversible ones get made today, irreversible ones get two more weeks and a lawyer.
The launch flopped and everyone saw it. How do I face people?+
Run the 72-hour protocol. Hour zero: state the fact plainly, no spin and no apology speech. Hour 24: one short message to the three groups who matter - customers, team, investors - with what happened and the next step. Hour 72: make the repair decision and name the one thing you will do differently. Performing shame in public buys nothing; the people watching take their cue from how you answer.
Is it weak to feel this bad about a number?+
No, and the feeling is not the problem - acting from it is. Rule: feelings get named in the audit, decisions get made from the ledger. Grief, fear and rage are information about what you care about and terrible advisors about Tuesday. Name them in the weekly audit, then take the next action a calm operator would take. Stoicism was never numbness; it was judgment that survives a bad month.
