Wealthy Affiliate is different than anything out there, and you will understand that as soon as you step foot into the community. We always recommend you get started on the free Starter membership, that way any insecurity or apprehension about this industry is removed. Then you can make your own educated decision as to how WA fits into your life/business.
The thing that I really like about WA is that even though I feel I have some good experience now (not an expert yet!), I realize that I can get help from someone with more skills and knowledge than I have at any time. There are experts within WA, many with MUCH more experience than I have that I lean on for support and to advance my own personal skills.
These ways of making extra money cover a wide range in terms of compensation and prestige. Check out the options to see what could work for you, keeping tabs on a projected per-hour rate so you can see what would be worth your time. The list is loosely arranged by 1. jobs requiring more skill or expertise, 2. gigs needing less and 3. things you can sell. And if you think of any good options I missed, please let me know in the comments.
