Whether you either passionately think we should stay in, or on balance think we should stay in, or on a balance of risks think we should stay in - for heaven's sake get out and vote in, because you might wake up and find out you're out.
Half a century ago, the amazing courage of Rosa Parks, the visionary leadership of Martin Luther King, and the inspirational actions of the civil rights movement led politicians to write equality into the law and make real the promise of America for all her citizens.
People feel that the EU is heading in a direction that they never signed up to. They resent the interference in our national life by what they see as unnecessary rules and regulation. And they wonder what the point of it all is. Put simply, many ask 'why can't we just have what we voted to join - a common market?'
When you're taking the country through difficult times and difficult decisions you've got to take the country with you. That means permanently trying to make the argument that what you're doing is fair and seen to be fair.
My view is, the most important thing as prime minister is trying to make the right judgments. In order to make good judgments, you need good advice; you need good principles, and you need a clear head, and you need to have a sense of equilibrium.
On the one hand we have got to ask, are there some areas of universal benefits that are no longer affordable? But on the other hand let us look at the issue of dependency where we have trapped people in poverty through the extent of welfare that they have.
Christmas gives us the opportunity to pause and reflect on the important things around us - a time when we can look back on the year that has passed and prepare for the year ahead.
2012 has been an extraordinary year for our country. We cheered our Queen to the rafters with the Jubilee, showed the world what we're made of by staging the most spectacular Olympic and Paralympic Games ever and - let's not forget - punched way above our weight in the medals table.
Today, hundreds of millions dwell in freedom, from the Baltic to the Adriatic, from the Western Approaches to the Aegean. And while we must never take this for granted, the first purpose of the European Union - to secure peace - has been achieved and we should pay tribute to all those in the EU, alongside Nato, who made that happen.
At a time when we're having to take such difficult decisions about how to cut back without damaging the things that matter the most, we should strain every sinew to cut error, waste and fraud.
Let me completely condemn these sickening scenes; scenes of looting, scenes of vandalism, scenes of thieving, scenes of people attacking police, of people even attacking firefighters. This is criminality pure and simple and it has to be confronted.
It does not seem to me that the steps which would be needed to make Britain - and others - more comfortable in their relationship in the European Union are inherently so outlandish or unreasonable.
The EU must be able to act with the speed and flexibility of a network, not the cumbersome rigidity of a bloc. We must not be weighed down by an insistence on a one size fits all approach which implies that all countries want the same level of integration. The fact is that they don't and we shouldn't assert that they do.
People are increasingly frustrated that decisions taken further and further away from them mean their living standards are slashed through enforced austerity or their taxes are used to bail out governments on the other side of the continent.
In a global race, can we really justify the huge number of expensive peripheral European institutions? Can we justify a commission that gets ever larger? Can we carry on with an organisation that has a multibillion pound budget but not enough focus on controlling spending and shutting down programmes that haven't worked?
After the Berlin Wall came down I visited that city and I will never forget it. The abandoned checkpoints. The sense of excitement about the future. The knowledge that a great continent was coming together. Healing those wounds of our history is the central story of the European Union.
We have the character of an island nation: independent, forthright, passionate in defence of our sovereignty. We can no more change this British sensibility than we can drain the English Channel. And because of this sensibility, we come to the European Union with a frame of mind that is more practical than emotional.
