So I do the reading, got a feel for what I should and shouldn't do and even have a business education and then find myself circling back with habitual errors. Hey I'm ok making a unique mistake but a bit self frustrated on the habitual ones that all the renowned writings, critique. Do you have any and better yet did you have a habitual mistake and found a way to beat it?
Some of mine are. Operationally * Inconsistent effort, with sprints then breaks. Result each sprint requires revisiting so I know where I was at. (start-up is part time, day job is current bread winner)
In Marketing: * Love to start the product before knowing there is a market. Result I'm sure you could predict.
Communication: * I find that I tend to be technical, vague and not interesting enough and so just not quite hit the exciting buzz. Result low to medium interst.
