This is reconciliation. The script is so focused and short compared to major titles, that reconciliation is the only thing that would cause “less energy.” Not to mention, the term “feel productive” doesn’t actually mean anything. Think about it, how does one “feel productive” versus not “feeling productive?” Does this mean you have a lack of motivation to get up and do things? Does this mean you’re feeling down and depressed about the likelihood of succeeding at whatever it is you’re trying to tackle?
When you dig a bit deeper, you’ll see that the subliminal processing is occurring – as indicative by you feeling “less energetic” on it – and your subconscious is reacting. Fatigue and lack of motivation is a common reconciliation symptom. You gotta push through and keep running it, as well as TAKING ACTION. If you’re just running the program and since you don’t immediately feel motivated, you just don’t do anything, you’re reinforcing the reconciliation. Get up and do something while running it. That helps the scripting kick in.
