Good "basic training"...
The good news about your challenge of working 9-5 then developing a business idea/plan in the evenings: it's great basic training for the reality of being an entrepreneur.
The reality of anyone running a start-up (including myself) is that the work doesn't end at 5pm (in fact, it could go 24x7). If our investors and Board members could have us work 8 days a week, they'd vote for it in a heartbeat!
GTD keeps me alive/sane in the entreprenurial world because:
1. It allows me to relax in the midst of uncertainty and focus on what needs to get done to move the business forward, rather than mentally rehearsing its failure by thinking about the overwhelming number of things I'm responsible for. It was the opening premise of Dave's book in this context that drew me to it in the first place. "It's possible to have an overwhelming number of things to do and still function productively with a clear head and a positive sense of relaxed control...", quoting from memory.
2. I am able to strike a balance between work and family (one of the toughest challenges faced by any entrepreneur!) - taking advantage of the "wierd times" as Dave calls it. Moving venture financing deals and customer/partner relationships forward, or setting expectations with Board members and investors are really transactional in nature, so 10 mins is usually enough time to move things forward in amazing ways!
3. I can track large numbers of "loose ends" - from a single-word change in a pending legal agreement to keeping my vision of the business alive with part of my weekly review dedicated to thinking at altitudes above 30,000 feet in Dave's terms.
Moral of the story: how you address the challenge of handling multiple, challenging roles and working long hours and having to make decisions when you're tired is great basic training for the challenges faced by even the most well-heeled entrepreneurs in the best-planned start-ups.
It would be interesting to get a group of people together to discuss specific applications and customization of the GTD methodology for entrepreneurs, though not wanting to lose the versatile/generic nature of this powerful approach.
