I disagree with you about your find not being valuable. It is priceless -
you have experienced the thrill and reward of the hunt.
Try to think of it as an opportunity rather than a setback.
You gained experience and insight in your past job and know what you like and don't like.
Follow your bliss and live life to the utmost. You will know
when what is right for you comes along. Build your skills, so
that you are less dependent on others - rely on yourself.
