At 25, I would have no hesitation in embarking on a career in aviation. You have time on your side.
If you are in a reasonably well paid job I would suggest you keep working and take the Modular CPL Route. It will take a bit longer but will save you a pile of cash and keep down your level of debt.
If you started a PPL tomorrow, you could have your CPL/IR in say two years. At age 27/28 you would be in a good position to get a job. You might consider instructing and acquire more hours before doing your IR.
I did all my training part-time, my exams through distance learning and did part-time instructing for about three years. Got my first and so far only flying job on a twin turbo-prop. in my mid-forties. For most of us it takes hard work and perseverence, even then, you need a bit of luck and there are no guarantees.
Go for it.
