If someone is not sitting in a lotus position and not observing his breath. Is he not doing anything? Say someone spends time doing something which is his present. Like when a mother takes care of her children. She is doing it as it is the requirement of the moment. She is not thinking about what she will get in return. So, doing your duty without expectation is meditation. However, when this duty is accompanied with meditation, there is no stress, frustration or depression.
Keep meditating.
