Lazy with any type of haircare: Top 10 crimes..

1. Tight/tiny braids at the front and nape to "make it neat". What they are really doing is giving customers alopecia.

2. Excessive blow drying with every wash making hair prone to breakage 3. Not moisturising hair as "dry" hair is easier to braids

4. Using those awful rat tail combs for natural hair causing micro tears/breakage

Latin America: 0.86
Asia: 0.79

At HealthCap Africa, we invest in only two sectors Fintech and Healthtech. One question I often receive is: what ties these two seemingly disparate sectors together?

Its often due to "Empire Building''. Let me explain.
This Halloween, Jeff Bezos dressed up as Batman and his fiancée as Catwoman. This is costume play. Everyone knows that Jeff Bezos is not Batman, and more importantly, Jeff Bezos knows that he is not Batman. Image However, what happens with corporate cosplay is that many startups don’t realize that they are startups, not corporations. They start spending like large corporations, try to look like large corporations & act like large corporations before reaching product-market fit.

This article took me years to write; not because the facts were hard to find, but because Aliko Dangote is an emotive subject. To some, he's an evil monopolist. To others, a ruthless operator. And there are many who believe billionaires like him simply shouldn’t exist. You’d be surprised how often people say things to me like,“If I had your kind of money, I’d buy 10 Chanel bags, a Rolls Royce, and only wear designer clothes.”

If you fly frequently, you know the drill.

When you arrive at the airport, police ask you for your passport and ticket before entering the airport. Then you scan your luggage. After this NDLEA call you for a physical search of your luggage.

Amazon are the masters of this idea of converting cost centres to profit centres.

For example, they realised that were spending billions with delivery companies like DHL and FedEx. Image By developing their subscription service "Prime" they were able to sustainably build their own logistics infrastructure, just like Toleram.

This helped them deliver cheaper, faster and more profitably to their customers.

Disclaimer. There are plenty of personal finance gurus on twitter, that's not me.

For this thread to make sense to you, you will probably need to be managing significant funds or helping someone else manage significant funds as an advisor. However, comrades who will be mounting flying bikes from our muster point in Alimosho to overthrow the Ikoyi bourgeois, please pay attention.

As after the revolution there will be significant funds coming your way. 😭😭😭😭
