You could use a little side table with wheels and put the coffee cups on it ,so you don't have to worry about spilling your coffee. I spilled coffee on the speakers before, and the speakers died.
I saw your coffee, and immediately went "ah shit my coffee. then reached for it to my left. its an iceberg. lol I suppose there is a price to pay for being excited about researching the new things for your M3 air MacBook. also love your vids man keep killing it!!
I worked jobs I didn't like for years while making content on the side, then as the content picked up I managed to leave my job and do this full time. It was a lot of work, and that's my main advice - find something you love and work on it until it pays off
