photofreak88, I'll second the advice from Paul and Chris. Here's my two cents, as a former pro.
It's important to learn quite a bit about the history of photography, the reasons for the lasting influence of certain "star" photographers of their eras, and the various markets for photography, if you want to figure out how to make your work stand out. Markets are changing rapidly, so learn how to research the buyers out there, and how to reach them successfully. Keep that up, because the changes just keep comin'!
Network all you can, in person, online, and by joining professional photographer associations. Listen/read much more than you talk/post at first. Practice the advice you collect, and see what works for you, both technically (how do I shoot this?) and compositionally (what do my shots look like?). Read, talk, think, and practice some more. Be glad that you're able to do all this practice digitally, rather than paying by the roll for your practice, because there's an old film photographers' saying: "The percentage of good pictures ("keepers") rises in proportion to the number of crappy pictures ("throwaways") you've made."
Invest in both training and in good quality lenses as you are able to. Master the use of your equipment. Study lighting theory and practice. Study small business management (no point in trying to become a pro just to go broke, right?) and marketing (how to identify and reach buyers). Make friends and acquaintances in many different lines of work and walks of life, and learn to see what their worlds look like. My own years as a pro came about because I used to hang out with aeronautical engineers who knew I was a photographer and gave me a tip about a job opening for a technical photographer at a testing facility. You just never know where an opportunity will appear, so be prepared and available!
Be patient and persistent. Go for it if you really want it. Good luck, and good shooting!
