If you're under 35 you shouldn't even be looking at this thread 😊. You're plenty young enough - go for it if it's what you want to do.
For those over 35 and, especially so, for those over 40 it becomes much more of a risk. The notion of being 40 something and having always wanted to be a pilot with no flying or aviation experience is simply not credible to recruiters. If you're in this latter age group then IMHO it's worth considering the following questions. The more of these you can say yes to the more chance you have of succeeding. If it's a no for all or most of them then it's really a risk too far.
1) Do you have no dependents ?
2) Can you afford the training (including TR) without taking on any debt ?
3) Do you have a fallback plan if it doesn't work out ?
4) Have you paid off your mortgage ?
5) Do you have savings/a career that can cover you after training whilst looking for a job ?
6) Do you have experience in the aviation industry ?
