Read The $100 Startup. Most businesses can be started with zero or close.

You don’t need to solve a problem. Cooy an existing business and do it better.

I’m a big believer that you have to love the process like no other to really be successful. Success is not the goal, but rather the symptom of falling in love with the process of building something

So I asked this founder friend of mine whose first startup did not do well after investing several years. After taking a year-long break he bounced back with another idea and a company. I captured this interesting conversation @ Journey to my second startup.
Tired of a lot of bullshit on this topic, I decided to talk to actual founders in the trenches to get their insights. Let me know in the comments there if you have any specific questions.

Take a skill from your 9 to 5 and form a 1 person agency around it.

All you need is a site, relevant experience/case studies, calendly and know how to network with right people to generate quality leads.

If you know your stuff its probably the least riskiest type of online business to start.

This guy didnt even take an existing skill, he just saved agencies time by curating leads for them and is making like $50k/m from his build in public growth strategy
