Here;s a nice way to feel good about yourself!  Make a list of everything you feel you are a success at, or have been a success at, or have done successfully at some time in your life....small things and big things.  Include all ares of your life, not just work.  Write down everything that has meaning for you, even if it might not to someone else.  The purpose of this list is to acknowledge yourself and your abilities, which increases your energy for creating and accomplishing more.  Keep adding to this list all the time with things that you have accomplished successfully each day.  Source:  The Creative Visualization Workbook by Shakti Gawain.
