An Article /video you should watch to see how someone who found a passion in something at the age of 15 has managed to indulge in that passion and make a good deal of money in the process. Check out: http://news.yahoo.com/blogs/driven/p-q-gubbio-meet-ian-purkayastha-19-old-134543761.html On a somewhat rant-ish note: many you you don't make much as webmasters. Not to kill your ambitions or put you down but if after a certain time period you are not making a living off your web earnings (assuming you want this as a principle income), you should stop and go do something else. Have the web stuff as supplemental at best. Looking at not just this forum but on others at their web based earnings, some would make more money begging on the streets. Where I live, even those who clean car windows at street junctions when the red light is on can make up to $200/day. Just some food for thought - don't let your ego get in the way of moving to do something outside of the web for monetry purposes. There are much safer and consistent/easier ways to earn money than being a webmaster out in the world.
yeah a lot of people aren't cut out for making it in this field. but if you find something you really love doing and got a knack for it, persist. selling truffles and banking, nice.
