I understand how you feel. I am fairly new to Tinderbox and have decided on a one step at a time and slower learning process when it comes to Tinderbox. It sounds that, like me, you haven’t got much time to sit down and work through the documentation. Experimentation can be enlightening but also deeply frustrating - especially with a live project.
What would be ideal would be a series of ‘how to’ training videos on something like lynda.com and I am hoping to make some videos in the future as I discover new ways of using Tinderbox. The problem is, of course, time. I am so busy doing other things, I can never find the time I need to create videos or do many other things that are on my general ‘to do’ list. In a perfect world, I would stop everything I was doing (or trying to do) and concentrate on just learning Tinderbox. That isn’t going to happen!
I see Tinderbox as a valuable tool and it becomes ever more useful to me but it is taking me a long time (and much longer than I thought) to get to grips with it. I’ll probably never master it fully.
My advice would be, stick with it and if you’re stuck, work with others to find a solution. I’m finding it is the best bit of software I have for collecting my thoughts and data.
