This is a warning for every worker in the UK. Have you turned down a pay rise without realising it? Millions have – around 10% of the workforce currently – and many others risk doing it, unaware of the consequences. It happens when your employer 'auto-enrols' you into a pension scheme, but you decide to opt out – in most cases, a huge mistake.

If you're under 22 or on a low income, a pension is probably the furthest thing from your mind, but what if I were to tell you there's a totally legal way, that doesn't need any negotiation, to make your employer pay you more money – possibly £1,000s over the years? Hopefully that piques your interest, and means you'll forgive me for not mentioning pensions in the blog title – but I wanted to ensure you read this.

I was invited on to BBC Radio 2 Vine's 'What Makes Us Human' programme. The brief: "Write then read out an essay on one unique element of humanity, interspersed with some autobiographical notes".

Which is better, the Help to Buy ISA (H2B ISA) or the Lifetime ISA (LISA)? I'm asked this all the time. No wonder, as they both offer an unbeatable, no-brainer 25% bonus for first-time buyers saving in them – yet there are some big differences, so I've bashed out an answer...

In June 2012 MSE joined the MSM Group and I pledged £10m to charity. As it was a public pledge, I believe I've a duty of transparency, so every couple of years I bash out a report blog (the last was Jan 19) to explain where I'm up to, and who gets the money. And 2020 was a year like no other.

As is now pretty well documented, I'm obsessed with statistics tracking my fitness. Each year I knock out an annual steps report. This is the one for 2020. According to my tracker, I did 8,889,800 steps – a ridiculous, hopefully healthy obsession.
