Good advice from Saucy Jack, aviation is a fickle industry and given the state of the pilot employment market at the moment it is wise to approach professional aviation with caution. You don't have to worry about your age, I have flown with FOs twice your age who have moved into flying as a second or even third career. I would say that the FOs who I work with who have worked in some other line of business for a few years before coming to aviation generally have a more balanced and mature approach to the job, but there are exceptions to the rule both ways! Make the most of your professional qualification, if possible get experience working in and leading teams and wait for the right time to come before embarking on commercial training.
