I followed roughly this path until I was in my late 30s. Now have a startup that is growing because we put in essentially 5 years of groundwork, while working full time day jobs, building product in an industry that isn’t sexy, being “lucky” (patient/observant) enough to ride a new federal regulation, having go throw away an entire product after 2 years and starting a new product in the same space/customers, showing customers we were in it for the long haul FOR THEM, with a well rounded seasoned founding team, business model first, taking the right amount of investment from the right investors at the right time.
In that way I think entrepreneurship IS actually a lifestyle, but the behaviors are not what OP alludes to. The lifestyle is falling in love with a problem or a type of customer or both and just seeing what you can do to help while building a business along the way…SUSTAINABLY. If your version of lifestyle is somehow BEING caught up in acting a certain way based on influence (I have no idea what an indie hacker is), that seems destined for failure.
TLDR. Go live your life, get a normal job to build security, don’t try and start a company at all, wait for a problem/opportunity to find you.
