Remaining flexible is much easier when you are basing that flexibility on your underlying qualities and talents. You are not starting from scratch (which can be really terrifying) but rather are looking for yet another way to express those very unique qualities and talents which are profoundly yours.
You don’t have to panic at the thought of entering a work world which seems like an alien beast, ready to devour little you. On the contrary, your inner qualities and talents are universal and timeless, and will serve you well regardless of the strangeness of this new world you are entering. Take heart! Success is around the corner.
