The success of any mentoring relationship is increased by building a framework which supports that up front. The balance you aim to strike is to adopt structure in a way that is helpful and not excessive, so it’s useful to consider how much structure you think you need early on. In the preparation stage, only you can decide how much structure is best and once you begin working with a mentee you are likely to adapt the approach.
Regardless of whether you consider yourself an ‘organized’ person or not, considering these questions up front, and deciding what you need or want, will help you feel clearer about how to progress. This clarity will benefit both you and the mentee, helping you to relax and enjoy the process.
