From Neil Gaiman:
Small acts of generosity, of speech, of reaching out, can mean more to those receiving them than the people doing them can ever know. Do what you can. Receive the kindnesses of others with grace.
Hold on. Hang on, by the skin of your teeth if you have to. Make art — or whatever you make — if you can make it. But if all you can manage is to get out of bed in the morning, then do that and be proud of what you’ve managed, not frustrated by what you haven’t.
