This requires moderate-to-high daily commitment of 30-60 minutes consistently, disciplined focus on foundational skills before stylistic experimentation, willingness to create many imperfect drawings, vulnerability in studying your own work objectively, and openness to iterative refinement. You need patience with plateaus, curiosity about different artists and techniques, the ability to critique your own work constructively, and sustained motivation through the period before your style becomes visibly distinctive. Financial investment may include quality ink pens or brushes (modest cost), reference books (50-100 dollars), and potentially online courses (100-200 dollars). Emotional investment includes tolerating the gap between your current ability and your artistic vision.
Growth Mindset Theory (Dweck): By approaching skill development as learnable rather than innate, you shift from fixed thinking (I can't draw like that) to development thinking (I haven't learned how to yet), which sustains effort through plateaus
