Don is a neurotic, single twenty-something failing to navigate his way through the very basics of life. His biggest enemy is his overactive mind, which plays out countless scenes of things he shouldn't do or say.

When Don moves into a house left to him by his recently deceased grandmother, he meets Eddie - his Nan's over-enthusiastic carer who doesn't want to leave. Don soon realises there are advantages to letting him stay.

To help pay off the huge back payments on the house, Don decides to get a lodger. He ends up choosing Abby, the girl he was in love with as a teenager and still fancies. The trouble is Abby isn't single - she has a snobby boyfriend called Karl.

Having become close to winning the heart of his ideal woman, Abby, in the last series, Don suddenly finds himself bereft at the start of Series 2. Oblivious and newly single, Abby has opted for six months travelling to get over her ex-boyfriend - leaving Don with both a void in his life and a spare room to fill.

Luckily, Don has Eddie to cater to his every need, which includes helping in his search for a new lodger. Eddie used to be Don's nan's carer but happily transferred his duties to taking care of Don, who inherited his nan's house.

From cooking and cleaning to cutting up his food, scrubbing his back and wiping his nose, among other things, no task is too great or small for Eddie and he's the closest thing Don has to a friend.

To make matters worse, Eddie has taken on Mrs Treacher, Don's elderly neighbour, who has become more eccentric than ever since her husband passed away. Eddie brings her everywhere with him - much to Don's dismay.

Don, however, soon realises that Abby might return from her travels still single and ready for him to waltz back into her affections. So this could be his last chance to play the field, plus it will earn him some extra cash. It's just up to Don and Eddie to decide who gets the spare room.

Our Review: The 2007 pilot of this sitcom was average at best, lacking both focus and reason. The first series was quite an improvement - the stronger premise (Don living in his deceased gran's house and plotting to dispense of Karl and win-over attractive Abby) and the new character of Eddie (David Armand in his best role yet) made all the difference.

However, Dan Clark struggled to make the self-centred Don likeable or believable during the first few episodes, something which no doubt put some viewers off early on. Those who stuck with it saw How Not To Live Your Life grow and mature (as a programme!), and many were enthusiastic when news came of a second series having been ordered.

Thankfully, that latter group have been richly rewarded. The second series of How Not To Live Your Life has been almost a different programme entirely from the first. Tighter, more consistently funny, and with some highly advantageous cast changes, the earlier episodes are almost worthless in comparison.

The good news is the show has been given a third series so there will be more from Don Danbury in 2010.
