Life is a Balancing Act, in some sense.
Too much of almost anything is bad. Too much alcohol is bad, too much computer gaming is bad. Too much work is also bad. Excess of things lead to negative compounding and the slippery slope fallacy wherein negative habits may derail and destroy an individual human being.
Too little of things may imply that one isn’t “living life” in the sense of “experiencing the pleasures” of life.
The happiest of human beings are the ones who keep their act together and keep things balanced in life.
What exactly “balance” is depends on that particular individual and changes from individual to individual, from time to time.
