Some people got it by parentage, some of us have to earn it.
You have to work your way up, doing everything required so you can have the freedom to focus on what you really love to do. Say you're an artisan who desires to build a company out of the craft. In the beginning, you are the one filling every single role in the company CEO, CFO, Technician, Customer Support etc. Doing all of this is necessary because you have to earn the freedom to focus on that which you really love.
If you're in a third world country where the jobs aren't there, you would have to do every available job to earn the job you really love. You might start out as a waiter at Domino Pizza even with your Bsc. That's the job that could make you enough money to buy a laptop, register for that certification exam, or even keep you going till you get your desired job.
All I'm saying is you might have to earn the right to do what you love to do. You gotta wear many hats to earn the privilege to wear that one hat you love to wear. When you're faced with that do not shy away from it.
A conversation in the movie The Pursuit of Happyness (2006) goes like this ...
Christopher Gardner : [after playing basket ball] Hey. Don't ever let somebody tell you... You can't do something. Not even me. All right?
Christopher : All right.
Christopher Gardner : You got a dream... You gotta protect it. People can't do somethin' themselves, they wanna tell you you can't do it. If you want somethin', go get it. Period.
