The lesson from the language - learning story is that consistency matters. Small efforts over a long time add up. And we should not be discouraged by slow progress at the start. We need to trust the process that good things will come with time.
We learn that perseverance is important. The artist didn't stop practicing even when his skills were not great at first. If we keep going, we can achieve good things. Also, it shows that we should not expect instant results. Good things don't happen overnight. We have to put in continuous effort over a period of time.
