Some people with OCD believe that their OCD does help them in certain areas, and in the short run, this is possible.
For example, the first few times you reread a paper for mistakes, you will probably find and correct some.
However, in the long run, helpfulness will most likely not be the case, OCD obsessions tend to get worse over time, rituals tend to take longer to perform, and the number of occurrences increases.
As your checking behavior gets worse, you may go from being satisfied with checking a paper twice to having to check it ten times just to be sure that everything is perfect, which is not a good use of your time.
Thinking that OCD is helpful to you is a slippery slope to tread on because the OCD will most likely just get worse over time, and you will feel more compelled to give in to it than to fight it if you think it’s helping you.
When you are at the point that you are giving in to your OCD, your performance does nothing but decrease.
