Anybody Ever Get Bored With Internet Marketing?

So a long story short-I started trying to make money online about 6-7 years ago. I started out full of enthusiasm.

I joined a network marketing company, got my company made website, and started driving leads through Adwords. I was ready to make my millions.

Even though I ultimately concluded network marketing wasn't for me (too high of a cost per lead and didn't like talking on the phone) I really enjoyed the camaraderie with everyone in the company. I also felt like I learned a lot (i.e. lead generation, over the phone selling techniques, etc).

I've since tried countless ways to make money online, with very limited success. That is completely my fault-I just haven't been dedicated.

Right now I'm starting an affiliate marketing blog (going to start at least 1 more shortly). I think my biggest strength is content writing. Since I know a lot about the topics I'm writing about, I figure it is my best chance of making good money online.

Here's the problem-it's BORING. After all, there is only so much you can write on the same topic.

I know it's important to rank for many different keywords. But after the first 5 blog posts, I'm finding myself largely rephrasing the same initial posts over and over in order to write new pages and rank for new terms.

Since there is only so much I can say on the same topic, I just keep regurgitating the same information in different ways. Needless to say, this gets very boring after awhile.

Do any of you ever find yourself getting bored with internet marketing? If so, how do you overcome it?

Even if I could eventually make 6 figures with blogging, I really want to feel like I'm growing as a person at the same time-not just doing the same thing over and over.

I'm thinking about branching out and maybe selling physical products on eBay, or learning copywriting. I just want to learn some new skills-not just do the same thing over and over. But even those things seem like they could get monotonous after awhile.

I think one of my main problems is that I hate sitting around. My current job involves a lot of physical activity, and I LOVE it.

Even though it's pretty much the same thing everyday, I really never get bored like I do with blogging. However, internet marketing involves just sitting at a desk all day. That is definitely part of the problem.

Any other ideas? How do others deal with boredom with marketing? Do you just "push through it"? Am I the only one who experiences this?
