We all know we should be drinking more water.
We also know that what gets measured gets improved.
We also tend to find any old excuse not to do stuff (such as drinking enough water) so the trick is to make things really easy.
To make sure you drink enough water, use a bottle with a measurement on it. Either buy a purpose made bottle with a measuring scale on the side of it (yes, you can easily get these) or just buy a large bottle of water and refill it first thing each morning.
Want to drink 1.5 litres of water each day? Then buy a 1.5 litre bottle of water, refill it every day and make sure you drink it all before the day is up.
You then have your accountability partner – the bottle (keep it with you throughout the day) – to check at any time in the day and see how you’re doing vs your target to get through that much water.
Simple but effective.
