It is something I could do p/t, and could always instruct/examine if the company permitted it.
It's short term vs long term really - go TP now aiming for where you want to be in 10 years, or take the short term risk of postponing career in the hope that in a few years you'll be able to pursue what you want to do free of many financial worries.
In other words, spend the next 25yrs working and paying the mortgage, or get rid of it in three then do what you want .... if you still can.
Anyone got a time machine they can lend me ???
