I always felt like if you get to a point where you've got enough money to invest in something real, you gotta invest in anything that's related to a natural resource because that's gonna be here forever - so you might as well invest in something that's gonna be here, rather than invest in something
In terms of instilling the values of mental toughness and work ethic, discipline is the gift that keeps on giving.
Up to that point I never really knew what my character would be expected to do, and prior to accepting the job I had actually turned down the role three times before finally giving in.
