We all have preferences about things. We all want to do things in specific ways. However, there is not always one way to do something.
For example, I am the type of person that would prefer to work hard on a large project and knock it out all at once rather than spend a little bit of time every day for a week getting it done. The thing is, whether I break it into an hour a day or just work for 5 hours on it in 1 day, I have still spent 5 hours total on said project. The outcome is the same. However, the feeling of sanity may not be the same.
When it comes to operating at your highest level, at any given time, you have to work in a way that makes the most sense to you. If you try to complete a project or work in a way that makes you anxious or distracted, then it could ultimately take you longer. The bottom line is there is no right or wrong way to do most things, you just have to understand your own preferences and the preferences of those around you so that you can adapt and operate in a way that suits you best.
What are your preferences? Where do you fall on this idea, all at once or a little at a time?
