For background, I am a 25 year old Software Engineer who works the corporate life. My company is moving to force engineers to work in person and I just do not want to keep working my life away. The pay is very high and benefits are great, but I know in the end, I want the flexibility of working for myself.

I have opened up some businesses in the past with mixed success. I want to open up a startup that can generate passive income, be a secure investment, and not require too much overhead. I have tried some eCommerce businesses in the past and even worked on a B2B marketplace like Alibaba in Asia.

I really have very little personal expenses since my house and cars are paid off. I have about 100k in savings that I can use for the startup.

I am facing a few issues:

Between long commutes and 8 hour work days, I have very little energy to work on a startup in my free time. Weekends and Off days are always just reserved for running errands and I have absolutely no time on weekdays. Should I quit my job?

The second issue I am facing is that there are so many different places to start. A physical laundromat business, a physical car wash, an online store, or a good old fashioned Computer Science startup. Any Advice on what to start would be greatly appreciated.

Lastly, finding a good business partner to help take some overhead is always a big problem that has caused me some headache in the past.
