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. 
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
You can prevent this (technically) by choosing the leverage(1:10,1:20,1:50…1:1000) I even did that, but it didn't help me because I was coping 8 different trades from 3 different traders. Psychologically you can prevent it, by being patient and, at the beginning chose ONLY ONE TRADER AND ONLY ONE FINANCIAL INSTRUMENT to copy. Do not copy not even 2 trades because you will see that in one day you have earned 5-10$( by doing nothing) and than you will start calculating what would happen if you increase the stake. So, DO NOT DO IT AT THE BEGINNING. Consider it as passive income.
You can set up a website, gradually build up the content (articles, videos, podcasts, etc.), then eventually monetize the site through advertising, affiliate marketing, or even the direct sale of specific products or services. Even better, you can generally find whatever services and technical assistance you need online and free of charge. Later on, when your site develops a reliable cash flow, you can begin working with paid providers who can take your blog to the next level.
If you have an eye for design and some experience of creating websites, then you could offer your services as a freelance web designer. You will need to create your own stylish website and have a few other projects that you can show potential clients to demonstrate your skills. You will also need to initially spend time emailing businesses to promote your services and find work.
Online business is how I’ve made a living since 2003 and what has helped me retire early. I make over $20,000 a month through my blog. You can create your own blog here with my easy 15-minute step-by-step tutorial. You can start a blog for as little as $2.95 a month (less than a cup of coffee!). Create a blog and leverage it into affiliate sales or product endorsement deals. Consider topics like:
A site called User Testing will actually pay you a fee to evaluate websites. It typically pays you $10 for each video that you review – which typically takes about 20 minutes. If the work is there, and you are particularly good at it, you could earn up to $30 per hour. That’s a pretty solid pay rate for a work-at-home job. You wouldn’t have to work a whole lot of hours to generate a decent part-time monthly income.
Join a startup accelerator: Another great option is to apply to a startup accelerator like Y Combinator, 500 startups, or TechStars, where a group of investors will help coach you, connect you with potential partners, and provide startup cash in return for a small stake in your company. The competition is tough to get into these, so don’t rely on them as your only path forward.
Perhaps one of the simplest ways to make extra money is to ask for a raise. This should really only be done if you have not received a raise recently, or if your job duties have changed considerably since the time you were hired. The worst that can happen is that your employer says no, but they might keep it in their mind that you would like extra compensation. On the other hand, you might get the raise, and you could end up with thousands of dollars more per year for 10 minutes of your time.
