I’m shooting for 15% – Most of what I write isn’t going to apply to You specifically. If we could see the spectrum of your skills and needs, it would hardly match someone else’s – that’s normal – we’re all very singular in our mental construction, our readiness and our Egos.
Additionally, your present situation is ever-changing. By next year these ideas will have shifted in their relative value to you. The ones you love now can become dull, while the ones you are skimming past now may become the most valued ones. It’s all OK – expect it, but plan to re-read.
And a word about veracity and trust: I have personally tried and used all of these ideas, so I know from experience and risk, that they can work.
