Your tastes, you say, are fixed; if they are so, you must be doubly careful to ensure their gratification. If you cannot make them subservient to external circumstances, you should certainly, if it be in your power, choose a situation in which circumstances will be subservient to them. If you are convinced that you could not adopt the tastes of another, it will be absolutely necessary for your happiness to live with one whose tastes are similar to your own.
