All things else being equal, it is best to select the business for which you have the best developed talent; but if you have a strong desire to engage in any particular line of work, you should select that work as the ultimate end at which you aim.

You can do what you want to do, and it is your right and privilege to follow the business or avocation which will be most congenial and pleasant.

You are not obliged to do what you do not like to do, and should not do it except as a means to bring you to the doing of the thing you want to do.

--The Science of Getting Rich by Wallace D. Wattles
