A trip into the mind of Wajdi

  Bad data visualizations are not just ugly. They are dangerous. A bad data visualization doesn’t just look unprofessional. It can make a good decision look bad, a small change look dramatic, or a serious problem look harmless. And the worst part? Most misleading data visualizations are not created by people trying to manipulate others. They are created by normal people who made small design mistakes. The data may be correct.   The conclusion may be wrong.  Because the visualization is wrong. Data visualization is not decoration. It’s decision-making. If a visualization is confusing, misleading, or hard to read, it is not a design problem ,it’s a communication problem. Over the years, a few fundamental principles have emerged from the work of people like Edward Tufte, Stephen Few, Alberto Cairo, and many others. If you follow these principles, your visualizations will already be better than most of what people see in reports, dashboards, and presentations every ...

While listening to podcasts, reading a book or scrolling through social media, some random quotes stick with you.  I've had the habit of writing down anything I feel I could use some day. I don’t really just keep quotes because they sound good. These aren’t from motivational posters or famous speeches. They’re lines I jotted down on a paper journal. Some are about discipline. Others about mindset. All are worth revisiting when you’re stuck or going through the motions. The 11 Words of Wisdom That Stayed With Me Trees don’t hang around with grass, even though they all started in the same place. Spend so much time on self-improvement that you have no time to criticize others. The magic you are looking for is in the work you are avoiding. If you are a friend for everybody, you are an enemy to yourself. If you always do what you've always done, you'll always get what you've always got. If you're going to try, go all the way. Otherwise, don't even start. Greatness do...

Prompts I use to 10x my productivity and time 5 Advanced LLM Prompts To Make Life Easier Why These Prompts Are Actually Useful Not being able to find time to share stuff is a hugle buttleneck. So I wanted to do a quick blogpost where I just paste my favorite examples of LLM prompts I used (and still use) to boost productivity and gain a little bit of time here and there. You’ve seen lists of AI prompts before, on blogs, websites, Tiktok videos... EVERYWHERE! Most of them are generic and are generated by LLMs. I built these prompts to work out of the box. They’re tested across models like GPT, Claude, Gemini, and even open-source ones. Each prompt forces the AI to output structured results — tables, summaries, plans — not just paragraphs of text. If you organize stuff, plan trips, read a lot, or manage projects, this is could be useful . Using smart prompts can save hours every week. What Makes These Prompts Better Most ...

 Hola! I've just written a very short piece about mindfulness. check it out to follow my train of thoughts, because this one is somehow an output of the how and the why to get to the what. Mindfulness is about being at peace, and one step closer to that peace is being able to accomplish things with the least amount of distractions. It seems that I'm starting to go "full on" at distractions these days... Don't mind me, I am in a long vacation, long enough to allow me to have some mindfulness and peace of mind to write these blogposts. We are drowning in technology in all aspects of our lives, especially when we spend the day at work, setting in front of a screen, batteling apps, tools and... distractions from notifications, emails, instant chat, system warnings, updates...etc Odysseus and the Sirens, Roman mosaic, second century AD.

It does not take saying too much, introducing the topic or blabbing for 10 minutes. Mindfulness, straight to the point and in few simple steps: Plan your day ahead. Your tomorrow starts today Sleep on time, enough to get 7-8 hours of rest Meditate right after waking up. 15 - 20 minutes should do the trick. Breath & slowdown, having prepared for your day, no need to run after the clock It is what it is, don't argue with what you can't control Breath, deeply..., when bad things happen. Exercise.

Why Consulting Firms Can Harm Business Growth | An Honest Take Before reading this, go ahead and read the below reference articles I listed at the end. So to apply myself to the previous post's mission statement (aka: write more often, about any topic of personal interest...etc.) I have some time on my hand here and I had a subject I long wanted to vent about. If you didn't know, I have spent a good portion of my professional life working for consulting companies. Overall it was 2 distinct companies operating in 2 different continents/countries. Pythagoras Emerging from the Underworld', oil on canvas painting by Salvator Rosa In-between, I have lived on the other side of the service contract, aka being the client. With this combined perspective, I have developed somehow a personal view on the value of consulting as a service, and as an economic agent, with a certain level of expected contribution to economic growth and developmen...
