"You can tell whether a man is clever by his answers. You can tell whether a man is wise by his questions."

Naguib Mahfouz

Distinguishing Personal Coaching from Business and Corporate Coaching is not quite right. Visions, values, needs, purpose, health, relations, alignment and spirituality are "topics" that across different fields that come under the heading of the coaching relationship. The focus in coaching is on WHO and not on WHAT.
Having clarified this, we can say that Personal Coaching is aimed at individuals who want to achieve what they desire or generate change.
The Personal Coach usually works with individuals in the areas of personal self-realisation and development, relations with others, life planning, and financial independence, but also on work and career issues.
The Personal Coach puts himself at the total service of the coachee. He does not judge. He encourages and supports, but also challenges people to go beyond their perceived limits, to not sit on their laurels, and to dare to think out of the box. Collaborative synergy is established in which the coachee can make important gains. Coaching is journey in which each step is as important as the destination.
In practice, personal/life coaching lasts from 3 months to a maximum of 9 months through weekly sessions of about one hour, held person-to-person or on the telephone.
