Wisebread is offering 100+ ways to make money, here is their great advice!

Ask for a Raise

You'll never know if you don't ask; pay rates are rarely straight across the board (unless you're unionized). You might just deserve a bit extra for your efforts. (See also: Ways to Boost Your Take-Home Pay)

Look for Another Job

If getting more money from your current employer isn't working, maybe it's time for you to take a step up. Look around to see what jobs are available; depending on your career, you may wish to align yourself with a headhunter who can job hunt for you (headhunters are compensated by the employers and are free for job seekers).

Start a Business

What are you passionate about? Can you turn it into a business? You never know — and it might not be expensive to set up. Find some inspiration here: Make Your Dream Career a Reality for Less Than $100

SIDE JOBS

These can be side jobs or even full-time jobs, depending on your situation.

Write

Writing is not a ticket to easy or quick income, but if you have a penchant for the written word, you can pitch articles to various editors of publications (online or in print) that you like to read, or you could even dust off some of that old poetry and see if it will sell. Here are some cautionary tips and tricks for making money as a freelance writer: So You Wanna Be a Travel Writer

Get a Sponsor

If you have a business or talent or website with a loyal following already, you might be able to monetize further with sponsorships. This is generally more of an in-kind form of income, with free products, tickets, and discounts in exchange for some sort of exposure.

Affiliate Sales

Again this is dependent on having a solid online following. Find products or services that are in your website's niche, and sign up for their affiliate programs. Digital products like e-books can pay up to 50% in commission, Amazon's affiliate program pays about 5% commission, and there is a myriad of options in between.

Tutoring

Whatever you know about — if you can teach it, you can tutor it online! From music lessons to language tutoring to business planning and coaching, with tools like Skype, Google Hangouts, and other video conferencing tools, just about anything is possible.

Check out these articles for some inspiration and 21 ways to make money online:

RECYCLING

Isn't it great when the stuff you don't need is worth something and doesn't have to go in the trash? Here are 20 or so ways to make money from recycling (heck — you can even make money recycling corks):

SELL YOUR STUFF

From using the likes of Craigslist and eBay to local target marketing efforts, here are a few ways to be rid of your wares and all the richer for it.

Cleaning House

Adam and Courtney Baker sold just about everything they owned (similar to myself) several years ago. The difference is, they applied more of a science to it, and I would surmise they profited better from it than I did using eBay, Amazon, and Craigslist: How to Sell Your Crap: Book Review & Tips.

Get Creative

In these articles you'll find sites and ideas like ExBoyfriend Jewelry (requiring your tragic tale of breakup in order to post your jewelry for sale), living estate sales, raid my closet parties, smartphone apps — and other creative ways of finding buyers for your stuff.
