Actress Tuppence Middleton has Obsessive Compulsive Disorder (OCD). It's not something she's really talked about before, except with a therapist. That is, until now. In this series, she's on a mission to find out more about the disorder - and herself - and to bust some myths along the way.Today, she talks journalist David Adam, writer of the best-selling book 'The Man Who Couldn't Stop' with the strap-line 'OCD and the true story of a life lost in thought.' David's OCD was triggered by an illogical obsession with contracting HIV/AIDS in the 1980s. He says each era has its "bogeyman".

Have you ever scrolled through social media and been surprised by an advert for something you were looking at the other day? This is no accident. Every view, every like, every click is stored, assessed and calculated, and allows the companies who run these platforms to target you with increasingly accurate advertising. But if you're not paying for the platform you're using, is there anything wrong with that? Well yes, according to Tristan Harris, one of the contributors to the successful Netflix documentary, The Social Dilemma. Social media may have started as a means of staying in touch with friends but it has led to multi-million pound businesses which use an economic model that competes for our attention, and Tristan fears this is doing society irrevocable harm.Marcus Smith is a content creator from Bristol and a digital native. He is fascinated by technology's impact on us and has studied the effects of online gambling on young people. For 'One to One' Marcus is looking at the 'tech for good' movement and speaks to two leading figures in the tech industry - one who argues that it is currently a force for bad, and one who tries to work with tech to harness the good.For this programme Marcus asks Tristan where he thinks we've gone wrong, and what social media companies, regulators and society should be doing about it.Producer: Toby Field

BBC journalist Sabet Choudhury donated a kidney to his mother five years ago. He says it was not a difficult decision to make. Once he heard she only had 3 years to live unless he stepped up, his decision was already made. The transplant transformed her life and Sabet says it opened his eyes to the whole issue of organ donation. During his personal donation journey he discovered that there is a lack of organ donors from Black, Asian and Minority Ethnic communities in the UK and this can lead to extra-long waits for a transplant. In this, the last of three programmes, Sabet talks to Saj Khan, a teacher from Birmingham who has experience of the emotional highs and lows of waiting for a kidney. Saj had his first transplant as a very young man, but sadly the kidney failed just after he graduated and he has spent years and years waiting for a new kidney.

Five years ago BBC journalist Sabet Choudhury donated a kidney to his mother. She’d been given just three years to live and the transplant transformed her life. Sabet, who is of Bangladeshi origin, says it wasn’t a difficult decision to make once he realised she could be waiting for years, because of a shortage of Asian donors in the UK. In this, the second of three programmes, Sabet talks to Faruk Choudhury. He is no relation, but he was Lord Mayor of Bristol in 2013 and he set out to increase the number of blood and organ donations from Black, Asian and Minority Ethnic communities in the city. This was happening at the same time that Sabet was coming to terms with his mum’s failing health and his decision to donate, so he followed the Lord Mayor’s project closely and sees it as part of his own donation story.

In this, the first of three programmes, Sabet talks to Kay Hamilton, his Kidney Coordinator, who played such an important part in his donation journey – and someone he has kept in close contact with since his operation.

But just what is success and failure, particularly in the creative industries? And who makes that judgement anyway? The fairy story we love to hear is that all you need to do is follow your dream, and success will be yours. But for many the dream does not materialise. They don’t get that lucky break. For others it’s just a long hard slog, and then there are those who reframe their ambitions as they go through life. In this programme Rosie talks to amateur actor and director Ben Hopwood about living his own dream - on his own terms. Produced by Jo Dwyer for BBC Audio in Bristol
