Painting should make you happy. If it does not, then you are probably in need of a tutor with another approach.
You could be struggling with te materials or can´t get the perspective right . You can do two things. Look for a good teacher or let loose, buy a box of acrylics-oils a big canvas, put on some good music that turns you on. And start putting colours on , follow your feeling. who knows, it could work for you!
But even better make an appointment to follow a workshop at studio Fatamorgana in Vlaardingen Holland see www.studio-fatamorgana.nl info@studio-fatamorgana.nl
Good luck
