Am I too old to switch careers?

To be honest with you, there are people who make a fortune in their twenties. So, if we refer to them, you are late. However, I think everyone deserves a second chance. If you are convinced that this is your true vocation, there are no problem. My only advice is that you have to motivate yourself, to be ambitious high enough to avoid wanting to change activities all the time.
