Often I'll tend to over-engineer the initial solution, but as I think about all the complex edge cases that needs to be handled etc I often find myself asking "does the customer really need all this".

After discussing it with the customer, a simpler solution often emerges, where they change the requirements slightly allowing for a much simpler solution that might even solve the actual needs better.

While it's not just down to experience, I'd say it has a strong influence on being able to see beyond the given requirements towards a better outcome.
