Hello ISTJs and ESTJs! In this video, you will learn how to use Introverted Sensing (Si), Introverted Feeling (Fi), and SF (Si+Fi) Sleep for ENFPs, ESTJs, ISTJs, and INFPs. This video will first define what Si, Fi, and SF sleep are. Then, I will provide a reference source so you can work on your Si+Fi better. Next, you will learn the importance of the SF (Si+Fi) and NT (Ne+Te) axis. You will learn the good use of Ne+Te and Si+Fi axis versus the bad manipulative way of using them. Finally, I will also provide my personal emotional examples on how to practice using these functions and animals. My goal here is to give ENFPs, ESTJs, ISTJs, and INFPs, a simple road map to help them practice their SF sleep last as well as lots of real-life examples on how it works. Check it out here:
