Getting a raise is harder than getting a promotion. Think about it from your boss’s perspective, would you rather a) pay more money for the same service, or b) pay more money for additional responsibilities. Regardless, sometimes a raise is in order, especially if you have worked for several years without one. Check out Ramit Sethi’s guide on asking for a raise.
If you want to clear some space out in your house and have a big stack of books you’ve been holding onto for too long, you can make money selling your books and textbooks online. Stores like Half Priced Books and others will give you cents on the dollar for each of your current books while you can check what your book is worth by simply entering the ISBN number on Book Scouter.
Again, if your blog has a large reader base, then businesses may be interested in paying you to review their services or products. Not only will you get a free trial using whatever these businesses are selling, but you will also get a fee for writing them a review and posting it to your site. Paid reviews (and other paid and sponsored content) can be big money, so advertise this service on your contact page to generate business.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
The music video, directed by Director X, was released on February 26, 2016. Speaking on the video's concept, X said that he wanted to incorporate the theme of "work" but "with a different approach." Initially, the setting was going to be in a "corporate office" but the idea was not executed as the group previously released "Worth It" in that same setting. Other ideas included a condominium construction set. He noted the reverse gender roles where the men are "the objects" as "opposed to the other way around" and the many interpretations of work, which he says aided in the song's success.
Blogging is a great side hustle because you can do it at your own pace anywhere you want. It's not a quick and easy way to make money, but there are a lot of ways to make money side hustling while blogging. You can sell advertising, become an affiliate for other people's products, sell your own online product, and more. It does take time to build up an audience to be able to make a decent amount of money, but once you have a large following, you could earn over $15,000 per month or more (we do).
Here’s a good example of how lead sales can work in real life: My second website, Life Insurance by Jeff, brings in a ton of traffic from people who are searching the web to find answers to life insurance questions. While I used to have the website set up so I could sell these people life insurance myself, it was a lot of work to process all the different requests and clients. As a result, I started selling the leads I gathered instead.
