It could be a good thing in the right environment like a startup.
Trying to organize then execute something could take a month of back and forth and planning. If you skip that step, you can get it done in a week then plan afterwards.
The only way I have found it working is to outsource my scheduling to someone else. I believe that explains why many people are diagnosed during college. College is much less restrictive than school and as a consequence people have to do their own planning.
