Some autistic people are prone to avoiding or procrastinating when it comes to doing tasks. Here is an excellent example of someone who struggles with getting some things done, yet excels at getting other things complete:
Leo (ASD) has trouble with certain tasks. He is very good at doing tasks that are compulsory such as work projects and paying bills, but anything that is sort of ‘desirable but not essential’, either never gets done or is left until the very last minute. An example might be the washing up – he won’t do it until there are no clean plates to hand. Or the housework. It just gets left.
