You might remember the meaning of the character 懒 with this easy mnemonic:
I'm a lazy person so instead of installing lights, I have lanterns (忄) hanging from that tree (木), and I use my mouth (口) to shave myself instead of using a proper razor (刂). I also use shells (贝) as bras.
Using mnemonics to remember the meaning of Chinese characters like has a huge impact on how long to learn Mandarin it takes.
