Bring your own water bottle.

Bottled water at a convenience store or mamak costs a couple of ringgit each time, usually bought without thinking.

Buy a bottle at lunch, another at the gym, another in the car.

A refillable bottle plus the office or home water dispenser. That's it. Nobody is impressed. The annual number is still real.

1. STEP 1Buy one decent bottle you actually like carrying.
2. STEP 2Fill it before you leave the house or at the office dispenser.
3. STEP 3Stop counting after the first week.

You’ll need: A bottle · Access to a dispenser or filter
