With new sectors like the retail sector opening up this is the right time to switch careers.
These sectors by the very newness are at the threshold of exponential growth. However, to sustain this fast-paced growth they need huge number of employees. Unfortunately, the newness of the sector leaves them with very little option other than to look for employees from other sectors that have transferable skills.
You can take advantage of their desperation by either cashing in on your transferable skills or equipping yourself with skills relevant to these sectors.
As I was saying this is the right time to switch careers.
