We all need to anticipate for change whether we have a job or are in between jobs.  Change is stressful but it is how you deal with change that can bring you success.  To survive and succeed you must sense change, make sense of change, and respond to change.

Product managers and product marketing managers have an advantage when it comes to managing change.  For the products you manage, you are already (or should be already) monitoring the market for trends, updating your product offerings to keep ahead of the competition, creating barriers to entry, etc.… in other words, you are already a change expert.  Now take what you know about marketing processes and apply it to yourself.  Manage yourself as a product that you are developing and launching.

Times are tough so below I have gathered a list of product management / marketing career resources to help my fellow marketers:
If I am missing important resources, please let me know and I will add them to the list. 

Change is inevitable and learning to deal with change will make you more successful.  Need some inspiration?  Then read  "Who Moved My Cheese" by Dr. Spencer Johnson, which illustrates the simplicity and importance of adapting to change.  It is a very inspiring, short, fun, and simple-to-read book.
