Curious to know what people think around having a side hustle to reach FIRE faster.

I started listening to Grant Sabatier’s books on FI and entrepreneurship and a repeated topic is to create businesses that provide more income that can then be invested into the market.

I know others like Scott Galloway advice against side hustles as they could become distractions from getting better at your job. There’s also a middle ground as recommended by Vivian Tu who says that people should try side hustles once they can “do their job asleep”.

Wanted to see if there were people here who had built any successful side hustles that allowed them to reach FIRE faster? If so, what kind of side hustle did you build? - i.e consulting, dropshipping, service economy, etc.

Would like to also hear perspectives from people that advice against side hustles.
