What is a skill or hobby you've always wanted to learn but haven't had the chance to pursue, and what's been holding you back?

I’ve always wanted to learn how to paint.

Every time I would see someone painting, my eyes would automatically try to trace the path of their paint brushes, observing the thin and broad strokes, the colours flowing and magically mixing into each other giving rise to a beautiful new one. I find painting perfectly fascinating.

I know how to sketch but not how to paint. Blame it on time, or majorly on my idleness that I haven’t had the chance to pursue it.

I have attached some of my sketches below though:)
