I am thinking about quitting day job and starting small business . I know there are lot of valiables but does it worth try for person whose annual income is approx 150k from job. Also I only have approx of 100k for investment in business.

On top of that, most people seems to be in gas station or restaurant business. What are other possible small business options , not looking for start-up or crazy tech shit, but more of traditional business , which can grow over time.
