Contrast From Baseline Is Important
Although having stability and staying at a high baseline may seem ideal, it is more important to have contrasting variability. Generally, contrast between highs and lows is what gives things value - i.e. you need the lows to appreciate the highs. If you are constantly at a high, then nothing will stand out. However, it is possible for variability itself to become the baseline, in which case stability is what would provide the contrast from the baseline of variability. There needs to be a balance in contrast between staying at baseline and variability.
There are many ways that this manifests itself:
You need to cycle through periods of chaos and order to grow as antifragile beings. Staying in order with a stringent routine - which may seem desirable - leads to stagnation and complacency.
Overcoming suffering may be part of the human condition that makes life worth living. If good things happened all the time, then you wouldn't appreciate the good as much.
Having a high baseline of dopamine is not the goal. The peaks from the dopamine spikes are what matter. If dopamine is always high, there would be no peaks from the dopamine spikes.
Travelling so much that it becomes the baseline, and you no longer experience excitement from travel. If you constantly experience new things, then the act of experiencing new things is no longer a new experience.
If you easily make deep connections with people all the time, then how deep are the connections really?
If everything was of equal value, then there would be nothing to aim at or strive for.
