Life and people often put so many demands on us, and sometimes the pressure can suffocate us, but it doesn't have to. I do my best not to use "should" in the way I think about and talk about my life, and I am working on eliminating "have to" as well. I either do something or I don't. I either want to do something, or I don't. I'm either assigned something or I'm not. I either have dirty dishes in the sink, or clean ones in the drain. I am not a slave to duty. I have the privilege of choice.
Let that knowledge sink in. Even if you have deadlines, you have a choice about how you spend your time. Do the things that bring you life, not because you "should", but because you CAN.
