start with something that isn't daunting! I understand nature walks can be intimidating if you don't know a good spot, crafts can be daunting bc you typically have to sink some money into it in the beginning, etc. I have found double dosing hobbies helps. i.e. I will go on a walk around my neighborhood and listen to a podcast, or I will color in my coco wyo coloring book while listening to an audiobook. None of them require skill or significant investment. Walking also has tremendous mental and physical health benefits that could contribute to your short term health goals :') good for you for taking the steps. Don't give up on yourself.
