I started my PhD last year in November. I've now heard of an incredibly attractive program that is just starting this autumn, with insanely good working condition (the salary is basically twice as high as my current salary and there are also nice internship options, which my program completely lacks.) My PhD advisor actually also participates in the program as an advisor. Thematically it is very close to what I am working on currently. I'm not unhappy with my current position or working environment.
Is it advisable to talk to my advisor about applying for this program? Of course, it is not very likely that I would even be admitted to the program, but it is so attractive, that not applying seems stupid. For different reasons, even though my advisor also participates in the program, I would not be able to apply for a position supervised by him.
I would have definitely applied for this program, had it existed last year. Also, when I started my PhD I did have the clear intention of finishing it, so some possibly related questions do not apply here.
