Hey there! If blogging is what you really think is most fun and you can earn enough with it to make a living then why not just go for it? Then you also have time to have some side projects wich maybe now are hard to accomplish with your regular job. I think its important to use your SP to help newbies with quality content to grow over time and stay motivated. Keep up the good work and Im looking forward to see some nice interesting new project of you :)
