As a clumsy person, I've had my fair share of struggles. I always end up spilling some water on the floor during water changes. I accidentally tipped over the bucket I was using for a substrate swap, so I had to start over. I spilled a water test on the floor when I meant to dump the liquid in the sink. I overfilled during siphoning and water got on the floor. I end up pouring too much water conditioner. It's frustrating. Not enough to make me quit, but I really wish it didn't have to happen as often as it does.
