There are four things you need in order to get the work done.
2. Energy & motivation.
3. The talents, abilities, etc... that are required.
4. The fourth factor is the organizational ability to put those three things together in a consistent way.
People typically think they don't have time, and many people are not confident in their abilities. Typically, lack of time is simply lack of organization. You can have a lot of time and still not get things done, or you can get things done in a narrow, finite span of time.
