There are lots of niches for income, using the various methods you described here. I think the most helpful advice you can get is to find something that won't burn you out so you can consistently do it over time. Don't worry if it's just pennies the first few weeks, just keep going. You'll see pennies double, quadruple over time as you show sustained effort in one or two areas with the highest quality you can afford to do. The more passionate you feel - that "Oh boy i can't wait" - the better for your audience, if your venture is sustained by audience reception.

• Consistency, every day, one thing!
• Suited to you, not a gigantic burden
• Best quality you can do and not too much
• Do research to make yourself the best version for the work you choose to pursue - blogging, video reviews, whatever
