It is a question of balancing your aspirations with reasonable expectations at your age.
If you can afford it, without putting yourself into significant debt, why not start the process of obtaining a CPL/IR.
1. Obtain a class one medical. No point spending any money on training if there is a problem here.
2. Modular groundschool first: Pilot mag ,and Flight International to name but two sources of adverts for this phase. The other option is a full time integrated course - say, Oxford, Jerez
3. Single-engine flying for the SEP[land] rating.
4. Multi-engine flying for IRT & MEP [land] rating.
5. Licence issue.
6. Flying Instructor's course.
7. MCC course if multi-crew flying a possibility.
Bottom line - employment is not certain at your tender age. Do the training as a challenge. Any employment must be regarded as a bonus not a certainty.
