I think those people are jalous!!! you have to use your free time like you want it urself!!! they have to watch their own work!!! I totally agree with the thing kustmace said!!!
My parents and family DO support me very good!!! My mom and her sisters are all artists (or have been;-)) and the brother of my dad designs luxuary yaughts...So I have both sides of the family that's used to be busy with the stuff... If I need something, I allways get money to buy it...not allways, but if I need it for school hehe...
If I dunno how to do something, I can allways call my uncle for help and stuff...(my mom don't draw products) and most of the stuff I can get from my mom, cause she has a lot of drawing stuff...thats also how I learned it!! I drawed since im a lil boy, but when I got older, my uncle learned me another technique...but good...this is not my lifestory hehe...my family does support me and ur family dont have to pick on you!!! just keep on drawing!!! do what you like!!! If someone likes fishing, he also spends hours and hours on it!!!
