Some good public sector building blocks are already in place. For instance, the Government is in the midst of its biggest ever international marketing campaign, with some private sector support, to secure sustained increases in trade, inward investment, tourism and foreign students. But, more is needed to maximise long-term economic and reputational legacy.
With Britain's Personal Best we are building on how inspired the UK felt after London 2012. It is a call for each and every one of us to dig deep and find something amazing that shows us at our own personal best. Whatever our age, ability or resources. It's about helping each other and ourselves, taking on a challenge that is intellectual, sporting, artistic, healthy or just plain scary.
This Saturday marks a year since Danny Boyle's glorious opening ceremony and just remembering those glorious two-and-a-half-weeks is spine tingling. We would never have it as good. Only we would just one year later.
In the past three weeks on the roads and up the mountains of France perhaps an opportunity has been starting to unfold. The greatest cycling race in the world, which in its centenary edition remains defiantly French in every detail of its character and organisation , is becoming a part of our British sporting summer too.
It's a bit 'last year' in 2013 to talk up 2012 but, as we approach the first anniversary of the London Olympics, there's good evidence that 2012 has changed what the world thinks about us.
July 2013 is most likely to go down in history as the month the heir to the throne was born (it can't be that much longer, can it?), but this week delivered plenty of other reasons to pop the champagne corks. Whether it was England's cricketers keeping the Aussies in check at Lords, the glorious weather continuing to toast the country from top to toe, or the historical moment when gay marriage finally became legal, cracking a smile hasn't been difficult these past seven days.
Needless to say, expectations are high of another successful run here at Flushing Meadows next month. Rugby followers may have noticed that two days before Andy Murray's achievement the British and Irish Lions won their first Test series victory since 1997, in Australia. So after a long drought we Brits are beginning to enjoy the taste of victory.
We can't afford to get cocky. Last weekend may be as good as it gets this summer. But Chris Froome in the yellow jersey and a home Ashes win would surely set the seal on a British summer of sport every bit as good as the one in 2012 we thought we'd never get close to experiencing ever again.
When I signed up to be a Games Maker last summer, I wasn't thinking beyond the amazing opportunity to be part of the 2012 London Olympic Games. The experience has been so much more to me than a summer of great memories - it's given me the chance to earn a nationally recognised qualification, boost my employability and get back on the career ladder.
For one joyful summer we wrapped ourselves in Team GB's Union Jack, stylishly redesigned by Stella McCartney . Of course it is a beacon of hope when that flag is worn to celebrate athletes whatever their colour, faith or gender, Olympian or Paralympian .
For the money the Brazilians spent on redevelopment they could have just levelled the Maracanã and built a new venue, but the modernisation has worked well and maintains just the right amount of history. The aisles are wide, the seats are comfortable, and the view to the pitch is excellent with fans feeling very close to the action.
From the moment the Paralympians exploded into the Olympic Stadium and onto our screens, to the moment Cold Play dazzled at the Paralympic Closing Ceremony, something profound happened. Risks were taken, a moment seized, and a nation was lifted by the power of possibility.
Few British industries are as strong as travel and tourism, and few have such growth potential. But achieving this will not be easy. It requires an unprecedented level of collaboration and partnership between the travel industry, the public sector and Government.
There may well never be another summer of sport quite like 2012. Yet every summer there is the potential for sport to excite and infuriate in near equal measure. The Lions down under, the Ashes over here, Murray seeking to match his victory in New York with a home Grand Slam at Wimbledon. All this and more are socially constructed, read these books not to distract from their entertainment but to inform and enrich.
British music, art, and culture in general has reached every corner of the world and this does create a favourable impression of the nation - useful for business and politics in addition to just feeling a bit more welcomed when visiting a new place as a tourist.
Whilst the Bank Holiday weekend's partying may have wiped you out to the extent that you feel like you never want to leave the house again, we reckon ...
