While I was away I spent a lot of time thinking about Minx's advice to stop spreading myself too thinly and to concentrate on what I really want to do in life.
It's good advice, of course. In fact, I remembered that I tried it once before.
Back in the mid-eighties I sold the businesses I was then involved in and took time out to write full-time. My wife continued to work and I became a house-husband and took a greater role in looking after our two young kids.
My main fear was that I would fritter away my time and not do any writing. I needen't have worried. Fear tied me to the keyboard. Every day between 9 and 2.00pm I plugged away at my novel. It was about corruption in the oil industry and had a host of extraordinary characters, based on people I'd met in the industry.
By the time a year had passed I'd completed the first couple of drafts of the book. I was also climbing the wall. I was lonely, isolated and suffering from sensory deprivation. I realised I could never tolerate the solitary existence of being a writer. I got myself a job as a business advisor. Within the year I had started another business - one of the ones I still own now.
After a suitable interval I re-wrote the book and sent it off around the publishers. No-one wanted it. I re-read it recently. It is rubbish, totally lacking in any kind of merit whatsoever, not even worth filleting.
So that's why I'm a little apprehensive about becoming a full-time writer once again.
