Trying out Game Design and increasing my Range

Decided to make a game. I figured since I am currently unemployed I have the free time to create things not in my area of expertise. I didn't so much as write that much on the script today since I have been busy procrastinating and working on so many projects I can barely think. To get into quality assurance or Games testing, I need to at least prove I can make a game and run bugs reports on it so this will be a chance to at least convincing employers that I have what it takes. Every time I go on these wandering amusements I keep recalling what my Dad told me about. "Jack of all trades, master of none" The problem with that statement is now into days economy that word of wisdom has become folly and now everyone has a side hustle or skill they got incase there current job, which is usually contract-based, goes south or their entire industry changes and becomes smaller due to automation or current trends, so they need to fall back on the second or even third skill. I guess I am just trying to convince myself that what I am doing is not a waste of time, but I have grand ambitions, dreams so big I can't fit on a page. Now I just have to draw a bow and get to it
