Should I Try It?

I have been blogging, on and off, for almost three years now, and I had signed up in a number of advertising platforms since then, some stayed, others faltered, in some I stayed, in other I run away *lol*. A few weeks ago, I received a letter, actually it is more of a note or a pamphlet from one of those advertising companies that I am currently signed with, it is a free pass to promote my blog through search engine marketing, I think it is a month's pass worth a hundred dollars or more. I didn't read it thoroughly as I have no plans in using it, as I've said a million times already, I am no whiz in this blogging business and taking risks in making it in mainstream is kinda far in my mind. I admit, I want to earn a little (who am I kidding, I wanna earn a lot) through writing and blogging but I just don't have the guts to fight with the crowd of professional bloggers that litter the net, I'll just take what I can and be glad with it, but I'm still hoping for bigger crumbs to fall though *grins*.

But I do wonder, am I just a weakling or am I being a coward? They say that opportunity only knock once so we have to grab it, in my case, I think, I have let go a hundred opportunities in this lifetime and some are haunting me, and now that another is coming my way, should I try it or just let it pass?
