贪新厌旧仿若天性
[tān xīn yàn jiù făng ruò tiān xìng]
This is more of a self-deprecating remark translating to 'Liking new stuff and forgetting old ones seem to be a natural characteristic'. It expresses human traits prone towards novelty, perhaps even criticising oneself or others latching only onto shiny and fresh things whilst neglecting those which had once held value.
