You say you're looking to grow your first 'stache, but honestly, it sounds as though you're way past that point - almost FI by all standards. You aren't - like the young, new starters here (myself included) - building your wealth starting from a five- or even four-figure net work - you're already at six, possibly seven.
Even though you're using an almost too cautious 2% WD, you're basically there once you sell your stock and/or move it to an index fund (which I think you should definitely do btw).
Anyway, what's with such a low withdrawal rate? What are you anticipating will happen? The only thing that has historically broken the 4% SWD rule is when your country has a nuclear bomb land on it (Japan, historical SWD 0.6%), so what exactly do you think will happen in the future that could be worse than the World Wars, the Great Depression and every recession since - that have all survived 4% (outside of those who lost those wars)? 3% is understandable, but 2% seems almost too bonkers imo. Not saying it's wrong, just wanted to ask.
And your last question, you fill your days by doing exactly what you want. The best advice I would give is to come up with some long-term goals that will stretch your creativity and skills in some way, that will also allow you to continue growing and learning. "Fill your days" makes it sound like one would just spend their time looking for things to do, and that seems too shallow for me. That's how you end up playing golf or watching TV all day. I'd say you have to work towards something - or even just join a club, start a hobby and pursue your interests.
