Looking for the key to unlock the job door

My feeling is that I've to go through a door. A big massive door. And just like in one of those "prisoners at the fort" competitions at TV that I never watch, there is no way around it.

If I'm going to pay my bills in the future, which is a prerequisite to live as I do, with a standard that I'm used to, I need to learn how to unlock that !"#¤%&/(* door.

To have some basic understanding of marketing isn't enough, in order to find the code or the key, I need to become a sales person. If I don't become a sales person who can sell myself I won't get a job. Unless I find the backdoor and it's unlocked...
