Meditation is often confused with meditatIVE activities. Sitting and trying to meditate doesn't mean you'll meditate, but meditation almost always requires you to sit still. When you're in meditation, you'll know - your mind will be in a different state (akin to sleep).
Keep practicing :) it takes a while, but once you get it, I promise it's worth it.
You can be mindful anywhere and at anytime. There are people who find skiing or other physical exercise relaxing because, after years of practice, they are being mindful in all the ways that matters to someone who sits on a cushion and "meditates". This is the end product of the "10,000 hours" thing.
The benefit from formal sitting practice is that you create a ritual container. A timebox. You align with the resolution and intent to practice. You dedicate this space, this time to the practice. However, meditation doesn't end on the cushion. You can realize all sorts of insights on the cushion, but can you integrate those insights when you're off the cushion?
