I believe the most important thing in life is happiness and satisfaction. Happiness can be with respect to career, friends, relationships and even family. When you’re forced to do or enjoy something, it’s just not worth doing it even if it pays you a lot. In your case, if you’re spending precious years of your life on a job which you hate waking up to, you can consider quitting. But I also wish to warn you about two things:
1. If you’re not satisfied with this job, are you aware of which job can give you the satisfaction that you desire? If you have that figured out, go ahead. Else, give it some thought. You don’t want to regret letting this one go.
2. Is your family or you relying on your salary? Make sure nobody is depending on your money and hence have no responsibilities attached with this job. Make sure you can handle months of having no cash. If it’s so, you may quit your job.

First, you need audience and presence; without either of the two, you’re going to have a tough time. If nobody knows, nobody buys. Second, you’re going to need funding, the term “you spend money to make money” is actually very relevant in marketing, because Facebook, Instagram, google and YouTube ads are not free. Next, you need psychological tactics, how to convince people to buy things, which the number one role is emotion. I hate to say it but, playing on people’s emotions is the only way sales are made. People buy because they’re sad and need comfort, happy and want to feel even happier. And of course angry, because then hey could use the purchased item to flaunt at their haters and enemies. Last but not the least, you need a really really good product or service. If your product or service is crap, it won’t matter if your marketing skills are great, 9 out of 10 times, people will move on to the product or service that does the work for them.
