Me trying to sound professional in English emails vs how I actually talk
Every single time. "Dear Sir/Madam, I hope this email finds you well" when I really mean "yo, quick question."
u/polyglot_painThe worst part is re-reading it 5 times and still not knowing if it sounds weird.
u/lost_in_translationGoogle Translate gave me "I am desiring to inform you" once. Never again.

That ramen spot in Shimokitazawa is incredible. Went there last month because of this video!

As a local, I'm impressed you found these places. Most tourists miss all of them.

冷知識：不一定要天天公開進度才會成功。有時候先埋頭做、安靜上線，讓產品自己說話更有效。
同意。一直發進度其實很耗能，反而影響節奏。
也不一定，曝光確實能帶來客戶，還是要看策略。

Stop overthinking your landing page. Ship it ugly, see if anyone cares, then make it pretty. Perfection is procrastination in disguise.
@sahilbloom this is exactly why most people never launch. they confuse "ready" with "perfect."
@katelyn_biz learned this the hard way. my first $10k product had a Notion landing page.

The Q1 campaign deck is ready for review. Open rate is up 18% from last quarter but CTR is flat.

Might be a subject line vs. CTA mismatch. People open but don't click — the promise doesn't match the landing.

Agreed. Let's A/B test two CTA variants this week. I can set it up by EOD.
