Right dude going to be real.
There's alot of solid advice on here and
@seo's is so fair.
I'm in the same sort of position as you. 19. Work in a retail store. Hate it. Trying to get this up and running so I can somewhat enjoy working and not hate my existence.
I study marketing in college so I have a natural interest in this stuff - as someone else elegantly pointed out, this stuff isn't for everyone.
Everyone (myself included) just heard the term "oh I work online from home making £/$/€x K per month and think OH BOY THAT'S SOME SWEET BANK I'M GOING TO MAKE A SITE AND MAKE THAT BANK.
What you fail to realise is that the reason they're making that bank is because of the COUNTLESS hours put in researching, testing, experimenting, talking to people, developing skills etc etc. If you were to work it out I'm sure alot of the people on here making money were working WAY for below minimum wage when taking into consideration how much time was invested into things.
Now look im not hating or being a prick I'm just saying this game isn't for everyone. Heck I don't even know if its for me yet. But not everyone can be good at everything.
Quick example I can think of is my parents. My mother is a great cook and it came to her naturally. She can whip up a great meal at a moments notice and with planning a meal she would put restaurants to shame.
My father however, if he was told he had to make a perfect meal or he'd be killed, he'd opt to make toast - and probably still burn it. On the flip side however, that man can do amazing things to cars. Things I didn't even think we're possible.
So basically if my father needs food, he would ask my mother. If my mother needed her car fixed she would ask my father.
See what I'm getting at?
I think honestly you need to give it a try. Anything. See do you like waking up to no exposure and low low rates for weeks on end until one day you'll get a sale or a hit and make a few bucks and be over the moon.
You just have to have a look at yourself and identify your strengths and play to them.
There's nothing wrong with not being a digital marketer and heck even if it doesn't come to you straight away but still putting in the grind - fair play to you, if I didn't like something I couldn't stick with it.
But for some people things come easier than others, and sometimes you need to realise when to accept that rather than fight it.
