Only you know if the juice is worth the squeeze. There’s no reason you can’t dabble in Real Estate while you fly.
Imagine looking back on your life once you retire....would you regret not flying? Would you regret not doing real estate?
You’re the only one who knows how you feel, but if Flying isn’t one of your passions you might be better served doing something else. The road to the cockpit isn’t always easy, paved, straight, or without potholes and detours, but if you want it you’ll get there.
