Replying to Graphic Design Security

I'm just wondering about graphic design job security, its been my plan for about a year and a half now to go into that career, it seems to be the only one that fits me, im still in highschool but im already designing a dj's album cover, am going to design a local rappers cover, and have done a lot of other things like that. I really like and am influenced by work by Hello Monsters and that style, and im just wondering if going into that career, designing albums, skis, boards, and things like that, would be a logical choice keeping in mind job security and pay.
