That "preparation phase" is exactly why so many people stall out before they even get to the fun part. You have to spend months, sometimes years, just building the "infrastructure" (the scripts, particles, basic grammar) before you can even begin to express a personality.
It’s like being asked to build a house from scratch but not being allowed to use any tools until you’ve spent a year studying physics. The sheer amount of "up-front investment" required before you can have a simple, genuine conversation is wild. Did you feel like the payoff once you finally crossed that line was worth all that heavy lifting?
