- you are strongly driven _by the idea_ of doing business, i.e., at some point in your evolution, you become Walt Whitman. A business, which
- solves a problem, makes a product, or offers a service, that
- you think can you do better and make money while doing so, and
- you would rather face the uncertainty of it not working out than be employed working on a thing you are not motivated by.
You should not start a startup if things such as exits, raising VC, optics of running a startup, or some such affair is of primary concern to you. They should be in the service of running the business and serving its needs, not the other way around.
This is not a script that applies to just some lifestyle, sustainable businesses, in the parlance of SV. This is the same script that even the largest, most profitable, and most impactful companies (cue the disruption adjectives) on the planet have followed.
