I agree, you are probably not ready to do a startup if you struggle to answer this question. I believe it wouldn't be an immediate rejection but a strong warning indicator. If a founder is not willing to commit to their startup full time, the startup is going to fall apart when all hell breaks loose. Founders that are half committed may have strong disagreements with each other when there is a conflict of interest (eg: too much time spent doing his full time job while working on the startup). Disagreement between founders can kill a startup. I suggest the author to find a full time job or work at another startup first. Do a startup when the time is right and you saved up enough money. If you decide do the startup, don't look back. Be committed to your decision.
