‘Set specific goals,’ is excellent advice. Why don’t people follow it? Because it’s difficult. Because they face analysis paralysis as they remember that to specify means to select from a larger pool of options. ‘Set specific goals,’ is the second step.
The first step is to see the large pool of options. In other words: understand the big picture and define the long-term goal.
After that, the details will fall into place. The tactics will become apparent. The specific goals will present themselves.
I also notice that ‘Not knowing what to do next‘ occurs when I don’t know what I want; when I haven’t defined the long-term goal; when I don’t understand the big picture; when there is no strategy in place.
Lower the barrier to entry.
Notice the obvious; articulate the broad goal first.
