To prepare for working with a life coach you need to budget time in your diary for a weekly session of around 75mins. I often provide homework and self study. When we work together we create a sanctifying space; if you like, you can make that space special, in your own way. Some people like candles, symbols, incense etc. while others prefer to be very formal and business-like -- its all ol, it is your time, just be you.
If you are unsure exactly what it is you wantto work on with Great Life Coach, then I highly recommend doing my 60 Minutes to a New You Free Life Coaching worksheet. This simple excercise will help you expose all that is wrong with your life and all that you want to change.
