Ultimately, it is your decision if you want to do it. Best of luck if you decide to embark on the journey. I know it is your dream and I hope you achieve it.
Just remember that you are entering a career that many people would do for fun and for free....er wait, actually there are people who do this job for free. If anything, this career is an excellent lesson in supply and demand economics. (and contrary to what you may have been told, there will be no shortage of supply.)
Good luck.
