There’s a relationship between doing something and thinking (planning, or dreaming) about doing something.
The thinking, dreaming or planning give a certain satisfaction, as if one were doing what needs to be done – or more precisely, achieving what needs to be achieved.
Working is not that gratifying, as results aren’t immediate.
There should be a balance between the two activities – planning and dreaming fuels your mental state and gets you in the mood for the actual work, and working gets things done and gives you real gratification.
When you’re planning to work, make sure you set time apart to actually do what you need to do. When you’re overwhelmed and don’t feel like working, plan or daydream with the achievement.
