Insecurities

Some creators wear their emotions on their sleeves. To understand these guys you have to understand the following (and this applies to Charles Schultz as well). These guys were victimized in school. Bullied and ridiculed (not all creators but you get an idea of who is like this the farther you read). So they post a webcomic and get a fan base and then it's a god complex. Now THEY have fans. So they feel like they are big shots. But they still suffer from incredible insecurity. So when someone criticizes them they have a flashback of being bullied but now they have power. They can lash out. You know what's sadder than the old rocker? The bullied geek who never let it go. Sad.

Seriously. Didn't you read the header? Move along.

Now is the time

Never before has the opportunity for success been available for cartoonist. The internet is a great tool. You want to be a cartoonist? Great. Here's how you do it. This is assuming you've got your strip ready to roll.
Get a website. Godaddy will allow you to register your site and offer hosting for a minimal monthly charge. Get a program to build websites (downloads.com has some just do a search for web design) or become familiar with html. Dreamweaver or Frontpage are both great programs but will cost you.
Get your comic uploaded then start visiting forums. Many of them have areas where you can pimp your stuff. Project Wonderful is a great way to get some traffic at a minimal cost as well. If your strip is well done and unique you will start to build a fan base and word of mouth will get around. It'll take a few years to build up a good following but it can be done. And the best part is you can do this in your spare time and still pull in a bankroll from your day job.

Paths traveled

I've encouraged you to get your degree and have other options in life. Why? Well, you're 15 and you like drawing so you want to do that. When I was 7 I wanted to be a firefighter. When I was 9 I wanted to be Spiderman. When I was 15 I wanted to be Hugh Hefner. We have dreams but as we age our dreams change based on our life experience. I'm not saying abandon your dreams. Far from it. I'm saying explore all options. You may say "I hate science" then you take a science class and realize that you love it. It's the green eggs and ham theory. You truly don't know what you do and don't like until you try it. Don't lock yourself into one dream. Keep multiple pathways open so you can choose which road you want to travel rather than letting the road limit your choice.

The Real Juggernauts

Two of the biggest comics on the web are Penny Arcade and Ctrl Alt Del. Both lead the pack in terms of numbers. Both understand the points of business and finding your passion and turning that into profit. Penny Arcade updated three days a week and it's safe to say that while, it's a webcomic, it's the blogs that pull the fans in. Both creators are gamers and have tapped into that culture being viewed as trusted advisers. And the industry has embraced them. CAD is similar. There seems to be some frustration regarding CAD among some webcomic fans but he's doing something right to pull in those type of numbers and make the money he's making. Penny Arcade and Ctrl Alt Del have both found formulas that will transcend the timeline that will kill most webcomics. They have grown beyond just being webcomics both are thriving businesses within the gaming community.

Hey Blockhead

Charles Schultz was a slave to Peanuts. Watch A&E's biography or read his biography and you'll see someone who couldn't get past his early rejections in life. It was the heart of Peanuts. Here's someone who had major success but still struggled with his insecurities. And worst yet he let life pass him by while he was chained to his drawing table. Drawing is great but don't do it at the expense of life passing you by. Life goes by quickly. He didn't like to travel and didn't like to take time off. He passed on family vacations letting his wife and kids go without him. He shunned offers of friendship because his friends and family were pen and paper. Even as he grew old and senile and his strip read like a train wreck and looked like a disjointed group of scribbles he refused to quit. He somehow equated his worth in life in his art instead of himself. Not a life I'd wish on anyone. But he was rich you might counter. What is all the wealth in the world if you don't enjoy it.
