The first thing you need to do when making a shift in your mindset like this is to stop focusing on what the end will look like and start focusing on what the next move will look like. This may fly in the face of what many say you need to do in order to cross the finish line, but visualizing isn't enough. You need to take small steps rather than huge leaps, and when you focus on the task at hand instead of the time on hand you'll be better equipped to do that.
The ideal scenario for one's personal productivity is to be both efficient and effective-not forsaking one for the other.
Task management and time management are very different. Knowing what you have to do and knowing how much time you have to do it require different mentalities. You need to learn how to manage your tasks first, then you'll be in a far better position to manage your time.
