Which is more proper holistic delopment or wholistic development of an individual?

The term "holistic development" is more commonly used and considered the proper form, as it emphasizes the integration of various aspects of a person's growth—physical, emotional, social, and intellectual. "Wholistic" is a variant that is less frequently used and often associated with specific philosophical or alternative contexts. Therefore, for general usage in discussing individual development, "holistic" is the preferred term.
