Age should not be a factor, you are young. Just keep some things in mind. Just because you love cooking home , does not mean you will like it on a pro level for 52 weeks a year 8 to 14 hours per day. Be prepared to work when all of your friends are home celebrating holidays and weekends.Be prepared to take a hefty salary reduction from what you are most likely earning now.To become a chef, is not only cooking, in fact that is least of your job. Its mediator, organizer,babysitter,operations manager,human resource coordinator,tasting and banquet consultant,director of sanitation etc. I may have forgotton a few things but just get the drift. Good Luck in any of your pursuits.
Just remember there is know such words as ''I can't do that".
