Be wary of falling into the trap of magical thinking with SaaS businesses. It isn't as simple as "oh, I'll just solve a problem and build a small SaaS business around, then live off the recurring income indefinitely." Competitors come and go, the value of your solution comes and goes with market changes, cost of doing business and customer acquisition fluctuates, churn happens, etc. Businesses are never at equilibrium. They are not magical passive revenue streams.
