It’s actually a no brainer: Make a business plan
Initial investment (training and cost of living during training) (A)
Expected initial salary - > career -> top salary -> expected career duration. This leading to professional life income (B)
Expected lifestyle and its cost (C)
Expected pension funds (company/self) (D)
Expected retired lifestyle and its cost for 20 years (E)
B - A = C
E - D = F
If C and F remain in positive figures, give it a try.
But don’t forget: In aviation there is a sacred rule, namely “always have an alternate”. This applies right from the beginning of your career!
