The referendum will be Scotland's biggest political campaign and will be fought in every city and town, village and community, workplace and home right across our nation.
It is a debate that will raise passions on all sides but one that must also be substantial and civil because the people deserve nothing less.
Since the launch of United With Labour, we have spoken to more than 500,000 people around the country, making our positive case for why our values and principles will best serve Scotland.
Over the next 12 months I will be supporting and campaigning for a bigger idea than independence, the pooling and sharing of resources across the UK, where we base our systems not on people's nationalities, but on their needs.
I believe devolution gives us the best of both worlds - a strong Scottish Parliament within a strong United Kingdom.
The questions we all need answers to are:
l What currency people will have in their pockets?
l What will their pay and conditions be?
l What tax will they pay on their income?
If you are in business:
l What regulations will you have to adhere to?
l What will the impact be on the free movement of goods and people in the UK?
l And, crucially for all of us, how will our public or private pensions be affected and guaranteed?
These are the important questions that those who advocate independence have to answer.
This referendum must be a change referendum.
I am determined that over the next 12 months we must give Scotland a campaign it can be proud of but, at the same time, set out the real constitutional, economic and social renewal our families and communities need.
We do that by building an economy not on any temporary economic advantage, or on a race to the bottom on tax, public services or living standards, but on one based on shared values of equality, fairness, community, solidarity and social justice.
All the polls in the debate so far seem to indicate the people of Scotland agree with this approach.
But the referendum result is far from certain and that is why we must continue to give a positive, principled and passionate case to remain part of the United Kingdom.
Families across the country are concerned about how they will put food on the table, are seeing their household budgets being squeezed, and are worried about whether their child will get into college, university or a job.
So it is crucial we do not allow Scotland to be put on pause and for a year to be lost in our pursuit of a fairer Scotland.
