I'm trying to fix my “staying informed” workflow, but I still spend way too long hunting for news

I've been trying to fix my "staying informed" workflow, and honestly I'm not sure I've cracked it.

I set up AI to send me a daily digest of what's been happening which helps. But I still end up spending a lot of time wandering around different sites, checking whether there's some big news I missed. The digest gives me a baseline, but it doesn't kill the FOMO, so I keep manually poking around anyway.

What are the 5 tools you simply couldn't do your work without?

This could be related to your industry, or even a side project you're working on.

Here are my 5 (I couldn't function without them):

  1. Grammarly proofreading my texts, not just posts, but also client communication

  2. ChatGPT / Claude mostly brainstorming, help with copy, and summarising

  3. Figma I can put the basic graphics together quickly.

  4. Translator sounds incredibly old-school, but English is not my mother tongue

  5. Gmail and not only for communication, but also for storing ideas and sending myself email reminders for posts

Which social media strategy worked best for selling your product? On which platforms?

Throughout the years in marketing, I ve witnessed many different approaches to how people use social media to sell a product (or themselves).

It always depends on the final customer; I can clearly see that companies usually bet on a few things:

their personal brand (often LinkedIn and X, e.g. Levelsio and Marc Lou for B2B, or Instagram in the case of influencers and their products)
purely paid ads (across Meta e.g. minimalist phone, where there is almost no organic content)
community-driven growth (Discord, Reddit, Facebook groups, Slack communities, etc.)
