Gratitude journaling has no right or wrong way, it is a simple act of penning things you are grateful for.
Doodling or colouring will let your mind take a break, helping you release your tensions.
Intention setting can help you focus on the things you are doing. It lets you overcome things that can give you anxiety by setting the right intention about it.
Walking outside and focusing on sounds, smells, and creatures around you will do wonders for anxiety.
Your to-do list can be mindful if done properly. While doing a task, dedicate your time and undivided attention. Do not multitask, and let one task take centre stage.
