" I can't help but make progress precisely through learning by doing; every drawing one makes, every study one paints is a step. It's true that it's like going along a road, one can see the steeple in the distance, but the land undulates, so that when one thinks one is there, there's another stretch that one didn't see at first and which is added on. However, one does get nearer. "
Vincent van Gogh, Letter to his brother Theo, 15 October 1883
The painting you do today may not be the result you're after, but keeping at it is how you'll get there. Tossing down your brushes in exasperation and not trying again for months won't. We'd like it to be easy, but that's an unrealistic expectation.
Van Gogh achieved what he did in a few years through persistence and relentless hard work. While you are unlikely to have a brother like Theo to support you financially while you pursue a dream, you can make the time in a busy life. Sketch while commuting, at breakfast or before going to sleep. Give yourself permission to put your art above something else demanding your time.
