Therefore, I am proud of the fact that I did manage to keep away and only kept minimal contact by email and phone. I surprised myself by my restraint.
My deputy took to headship like a duck to water, and she and my excellent leadership team ran the school perfectly well without me. Distributed leadership really does work but I can't help feeling a little put out by their self-sufficiency.
I suppose it's only natural - we all need to be needed. I wonder how we will adjust once I return to school, and think about what we might do differently.
During my term out I have visited eight schools, spoken at five conferences, participated in another six, attended four meetings and spent a day at the General Teaching Council. Added to that, I made one appearance on TV, wrote three articles for The TES and read a newspaper every single day. I also read nine novels, had two dinner parties and occasionally "played out" on a school night.
So, how did I manage to get my research done, I hear you ask? With great difficulty is the answer. I read countless academic books and papers and have written more than 15,000 words. Now all I have to do is string them together so that they say what I want them to say and make them sound like me.
My tutor warned me early on that writing an article for The TES is not the same as writing a dissertation. He says I can't just say what I think; I have to back it up by finding examples of others who think the same way.
This is very difficult for an opinionated headteacher who is always right.
But I am sure it is good discipline for me. I can't promise to change my ways and back up everything I say with references to other authors, but I hope I might be a little more measured in my responses in future. But don't hold your breath.
I thought I would share some of the lessons learned while I have been away from my desk. First, it is clear to me that I can never retire - I love my job too much and I need people around me.
Second, following a dinner party discussion, my guests agreed that my obsession with work and education is similar to being addicted to alcohol or drugs. Therefore, I want to own up: "My name is Kenny and I am a workaholic!"
And third, the reason I do not go to the gym regularly is not because I do not have the time, it's simply because I cannot be bothered.
I also realised a truth universally known - once a Catholic always a Catholic, at least as far as guilt goes. This has meant that I have not taken the opportunity of writing my study on a sun-kissed beach in the West Indies. Quite the opposite. I worked through weekends and holidays because I must finish my task.
Despite the hard work, the stress levels are not the same as being at school. I am told I look years younger, but the truth is, I thrive on stress. It may not be healthy, but it's me. I am at my most creative and innovative when under pressure.
I recommend a sabbatical for all heads (and all teachers) who have been in post for 10 years. My sabbatical has allowed me to reflect, to think, to read and to gain a different perspective on life and work.
I know I will go back re-energised and even more enthusiastic than ever before. My school will benefit as a result. My deputy and leadership team have been given the opportunity to lead the school in my absence. I always knew what they were capable of and the experience will help them on their journey towards headship.
I therefore urge school governors to consider adding a sabbatical entitlement into every head- teacher's contract. It might help to encourage more colleagues to take up the role.
