Nearing design parity

This is so damn scary, but also so damn exciting, but so scary! I'm nearing design parity with my old system vs new system. This basically means it's time to *sell* my product back to my previous employer, with massive upgrades, as a full replacement. Then, sell to everyone else that uses the same system, rinse and repeat, make millions. I'm building an entire tech business in secret, alone. I know it'll succeed in my gut, but damn, this is stressful. Ketamine these days: Lets me focus my thoughts on things that I *want* to think about, vs the worrying, negging, bad programming thoughts that creep in. Grabs my stress, and rips it out of me in the form of tears. My subconscious latches onto the first thing that'll make me cry, and bursts the levy. I read somewhere, cortisol, the stress hormone, only leaves your body through sweat or tears, so this makes sense.
