My goal has been to learn Mandarin Chinese and traditional Chinese characters. Specifically, to read a newspaper, write and type in Chinese, and converse well-enough to (for example) ask meaningful questions at a museum.
+ Three Character Classic, 1000 Character Classic
These are resources that I have found the most useful, and would recommend to anyone learning Chinese.
+ Learn zhuyin and pinyin
+ Practice tones and tone pairs
+ Develop comfort zones, 舒適區
+ Focus on Forms 語法
+ Beginner: children shows (like 我在哪裡, Magic Marker)
+ Intermediate: subtitled shows (like Happy Chinese)
Other (helpful) resources
These are resources that I tried, but ultimately found to be lacking.
+ Michel Thomas, unfun and sleepy, misleading explanation of tones
+ Pimsleur, boring, bad audio
+ ChineseSkill app, too buggy, unfun
+ ChinesePod app, giant advertisement asking for money
