Yes I had a lot of people against me too Sissi. When I told everyone I wanted to give up Engineering (A stable well paid job) completely to do photography I got some odd looks. The thing is its my life and I want to be happy, so I made my choice, had some tought times, then things started to get better. You just have to set your goal and go for it, dont let anyone tell you no. Thats my advice Thats my 20c.
In Australia we also have whats knows as the "Tall Poppy Syndrome". Its where some people that get jelous try to bring down the succesful people. Even though I always put myself out there and make myself available to anyone for questions etc. there are still some very nasty people who make it their job to discredit succesful people. Its all part and parcel of having success in a very competitive arena.
I love my work, I love my art, and im going to do it for as long as i can.. until my last breath, hence my business SLogan "The Passion of the Art".
