Here’s my favorite resources on Self-Improvement:

Feng Shui Explorer guides on using Feng Shui. Check out the tutorial video on that page first.

Yi Hexagram Plotter.  I use this together with my Yi Jing Guide in making my decision.  I also have the Yi Jing cards when I can do this without going online.

Bazi Chart when I can generate my Natal and Yearly Bazi chart.  There is also a 2-hour update on the Door open on that timing.  Bazi is about life destiny.

Xiao Liu Ren 小六壬 is a technique that I used to make quick decision without need for any other tools.  This video show how to use this or this second video.

Chinese Calendar Tongshu show the readings of the day. It also shows the Auspicious time of the day.  Use this if you do not have the whole tongshu calendar.
