That’s a huge question to ask, and it’s not that clear on what kind of influences it means. Does it just mean gaming influences? Hard to know.
Then there’s the matter of how you’re influenced and whether you even know you’re being influenced, and in what way.
Not to mention things that influenced you in the past may not be the same things that influence you today. Things change, people change, hairstyles change, interest rates fluctuate…
