All skills and growth have an invisible period of accumulation. Before reaching the tipping point, it's hard to see results, so people tend to get anxious. It's not actually a matter of ability, but rather a lack of understanding of the rule that "quantitative change leads to qualitative change." True transformation never happens suddenly; it is the concentrated manifestation after long-term accumulation. Endure that time when no one responds, cross the tipping point, and all persistence will begin to pay off.
