Some folks sit, fold their arms do little to nothing, and expect money to start flowing. Below are why you might not be able to make money online;

1. You have no skill: There is no online central bank where you can pick money. If you must make money online, you must have a skill that you sell to people who need it and then pay you money in exchange for your products or services. There are thousands of skills that are in high demand, check online and you should be able to pick anyone of interest to you.
    
2. You want quick results: Earning money online takes time. You do not just come online today and start making money. You have to learn a skill, even if you have one, you have to show your consistency by working and showing results before people start to trust you to do business with you. You went to college, did you graduate to fall into wealth? Of course, you started from scratch and built up.
    
3. You don't want to spend money: If you are not willing to spend money, then you need to quit online. There is no free lunch anywhere. You must be ready to invest money in advertising, learning, work tools, etc to be able to earn. The most important thing, you will not get it free, those you will get for free are mostly saturated and will earn you little or nothing since everybody now knows about it, what will you offer differently?
    
4. You don't want to practice: The only way you can become an expert in whatever you do is to practice. Don't quit too soon. You need an average of one thousand hours to master any skill. So why would you quit on a process when you have not even invested up to that learning, making mistakes, relearning, and unlearning? If it's that easy, believe me, everybody will quit their offline jobs and come online.
    
5. You don't give free stuff: The best way to sell is to gain trust. The best way to gain trust is to offer what people are looking for 'free'. You must be able to share information, tools, etc as freebies so that they know they can trust you to buy and know you will deliver.
