Reason for seeking alternative employment

[Georgelassosthemoon]

I'm applying for a new job because my current one is simply too long a commute (3+ hours a day). However I'm a bit stumped as to what to put in the 'Reason for seeking alternative employment' box on application forms. 'Because I'm a lazy bugger and would like to see more of my kids' would be the honest answer. The jobs I'm applying for are all similar to my current role so I'm looking for something positive to say but struggling to find the right words. I've used the commuting distance reason on a couple of applications in the past but I've felt it was a bit negative. Any ideas please?

Its one of those daft questions really - I would say shorter commuteis ok - but also if you can say anything positve about the organisation or the role put it in

It's a common reason these days. Working nearer to home is becoming more popular as people realise the importance of a work / life balance.

I always put 'career progression'. Then if they question it say you are seeking new challenges in a new company.
Simples.

Thank you all - you've given me some good ideas. I like the sound of new challenges!
