This year it will be ten years since I was diagnosed with breast cancer. I know I am one of the lucky ones – my cancer was treatable and NHS staff were skilled and compassionate.
I’m unbelievably grateful. One of the things it taught me was to make the most of every single day – because no one knows how long we’ve got.
As time has passed since my diagnosis, however, I think I sometimes forgot how important that is.
So my resolution is really simple – to remember to live in the moment, right now, and be thankful for my family, my friends, my dogs and for being alive.

Forget the pyrotechnics, some of you may get to welcome the new year under nature's own fireworks display.
Following a recent coronal mass ejection from the Sun, there is the possibility of seeing the northern lights overnight.
As is usually the case, it's the far north of the UK that is best favoured for seeing any possible display, and in parts of central and northern Scotland cloud breaks are likely at time to allow a good view of the sky.
You will need to wrap up well and be patient, should the aurora make an appearance, as it will be turning much colder from the north tonight. Rain, sleet or snow showers will also punctuating the clearer periods at times too.
For most other parts of the England cloudy skies will spoil any chances. A few breaks in the cloud in the far south are possible, but the chance of the northern lights being seen here is always more limited and dependant on the strength of display.
2025 is well under way in Sydney.
In the minutes before, a countdown was projected onto the Sydney Harbour Bridge, with thousands joining in for the final 10 seconds.
As midnight struck, music boomed across the city and fireworks - as great in number as they were in variety - lit up the skies.

In Spain, it's customary to count out a dozen grapes and eat one with each toll of the bell at midnight.
This dates back to 1909, when vine growers in Alicante had too many grapes to sell and needed a way to boost their popularity.
Don’t be offended if a neighbour lobs a plate at your doorin Denmark - the gesture is meant to be affectionate. The more plates chucked, the more luck you’ll have in the coming year.
Save your most colourful underwear for celebrations in Latin America, where donning them on new year is meant to bring you a different type of fortune depending on the colour. Yellow brings wealth, red brings love, for example.
In the Philippines, people will surround themselves with round objects, to represent coins. Wearing polka dot clothing and eating grapes is common choice.
We can now bring you some images of the fireworks display over Auckland - cementing it as the world's first major city to welcome 2025:
New Zealand ushers in new year with firework display
The clock just struck midnight in New Zealand and Auckland is marking the arrival of 2025 with its traditional fireworks display at the city’s iconic Sky Tower.
The North and South islands lie in the same time zone but the Chatham Islands - some 1,088km (676 miles) east of the South Island - is 45 minutes ahead and has already kicked off celebrations.
We've just received pictures from Australia as the country approaches the beginning of 2025.
A "family fireworks" display has already lit up the Opera House and the Sydney Harbour Bridge, displayed three hours before midnight every year ahead of the main show at midnight - or 13:00 GMT.
Revellers are already setting up camp by the water to ensure they get a good view later on:

It’s just gone 10:00 in London and the island nation of Kiribati in Oceania is now the first country in the world to have entered the new year. I wonder what the future's like..?
The country - pronounced Kiribass - is made up of 33 atolls and occupies a vast area in the equatorial Pacific Ocean, stretching nearly 4,000km (2,485 miles) from east to west and more than 2,000km from north to south.
It marks 20 years since they changed the time zone across the international date line, which led to an unusual event of Kiribati's New Year's Eve in 1994 being celebrated on 30 December.
Another unconventional result was the nation being 26 hours ahead of neighbouring Baker Island (a US uninhabited territory) - despite being nearly 2,200km closer to the Western Hemisphere.
Happy New Year to all there - we'll be joining you in 14 hours.
Image source, Getty ImagesIf you’re really looking forward to celebrating the end of 2024, you can ring in its successor 38 times across a 26-hour period. Here’s a few key times to watch:
By the time Baker Island in the central Pacific Ocean leaves 2024, it will be 12:00 GMT - by which point it will already be 2 January 2025 in Kiribati.
