What is the Idea behind TIPs?

I graduated from Design School as a Product Designer. I was evaluating my learning cycle. I've discovered a simple formula! Consider a simple example: if you'd like to draw well, you must get a pen first; this is the "TOOL." Then it would be best if you had a simple "INTRODUCTION" to learn the basics of how to make lines and shadings etc. Finally, you have to "PRACTICE" with some case studies or templates.

I've collected this trio as TIPs, a.k.a. Tools, Introductions, and Practices.
