Need some feedback on how to pursue multiple streams of income...

For side income, you're looking for:

• Quick to get started

• Fairly reliable chance of working

• Monetizes at small scale (i.e., charge people directly)

• Low requirements for maintenance and support (including time, urgency, and drama)

• (And arguably: not too emotionally draining since you'll already be giving your highest-energy hours to your job/family)

The "normal" answers fitting those constraints are:

• Info products (PDFs & course are fastest to get started, but also tend to require actively driving traffic from somewhere -- other options like books also exist but have different tradeoffs)
• Productized service (e.g., preparing people for a promotion interviews or feeding back on their product plan/roadmap/whatever; becomes hands-off once have enough dealflow and process to train freelancers and let them handle the delivery)
• Famous-as-a-hobby (e.g., youtube channel, newsletter, podcast -- monetizes extemely slowly, but is attractive to some people since they enjoy the core activity and it doesn't feel like work)

None of them is perfect, but there's no such thing as "easy" money.

If I was personally really in a hurry to make a bit of hands-off income, I would essentially do niche SEO around udemy courses, trying to make a course in a weekend and continue until I had 10+. (And you can always somewhat scale it later by building an audience.)

What's the biggest challenge PMs face? How are they solving it? Is there a way that this problem can be solved better?

If you're a PM (a project manager instead of a product manager I assume) at a startup one of the biggest challenges is probably related to processes - setting them up, automating them and documenting them. Once in place, then you have to ensure people follow them, align incentives with them, etc. Does this sound like an interesting area you can explore?
