I don't think it's a bad suggestion to continue or even start your flight training this year. Provided you do it modular and do it part time, you won't be ready for another 14-18 months anyway. The trick is to take your time with just enough exposure to keep you in touch with aviation whilst not sacrificing your other job. If you're ready by end of 2021 / early 2022 but there's still no pilot jobs, so what, go back to your old jobs. Then save your cash, ready to hand over for type ratings and the like. When hiring booms come, they can also be gone in a matter of months or even weeks. The important bit is to be ready. A 2 year old bare bones fATPL is just as good as a 3 month old one. Don't let anyone tell you otherwise.
