How much does it cost ... and is it worth it?
One rule-of-thumb, according to several coaches, is that coaching takes from three to six months if you want to make a significant change. Ordinarily, you have one session every other week, and you get at-home assignments to do between sessions (such as formulating a goal, or making contact with five selected people.
It usually takes two or three sessions to get to the heart of why you really need coaching, and then a while to make a real change. The prices vary depending on where in the world you live.
Is it worth the money? Only you can answer that question. Some people can fork out $5000 US for their personal development and feel that it was worth every penny, even if they have to take out another mortgage, while others are high-income earners who think that $200 is daylight robbery. Money is a question of values.
