saved a painting

I was doing a landscape painting using Acrylic. Acrylic's fast drying nature itself drives me crazy. To make the things worse, this lanscape had a rugged, exposed rock in the foreground. I tried painting it and failed miserably. I was just putting colors and there was no texture. Texture was so intricate that I felt like taking a pencil and do the shading but I was using brush. Rock had various colors too.
Me, neither do I know how to mix those colors nor I know how to get the texture...

Frustration came out and I took different colors and splashed over the rock recklessly. Thus I killed a dying painting...I did not want to look at that painting...I removed the painting from the easel and placed over the bed....I felt really defeated and beaten..
I do not want to be beaten in painting...I took the paining back again and reworked on the rock. This time I used brush as if it's a pencil and got the some decent texture...
At the end of this emotional drama, I had my first ever texture painting and it was quite decent. I had heard about painters undergoing frustration and I just tasted for the first time...
Any way I am very happy that I saved my painting and also discovered a method to make texture painting...
