As you work to achieve your goals, things will not always go according to plan. You will need to adapt.
Knowing your purpose and values in advance will enable you to identify more quickly which issues matter to you and which you can ignore. It will bring you faster decisions, clearer outcomes, more focused resources, better motivation, flexibility, and results.
In a churning world, the one thing you can guarantee is that the journey you have chosen will not turn out the way you expected. So as well as being clear about where you want to get to, it is also important to define why you are making the journey and how you want to get there.
