i've taken notes for a while, but in the end considered it to be a waste of time (other than that it helped me remember thing more easy at first).

like any other diary, you won't re-read it and if you run into an issue of which you know you've faced it before, chances are that your written down thoughts are that unstructured that solving the issue for a second time probably takes less time than trying to find the solution in your notes.

so if writing down the issues you're facing and their solutions makes it easier for you to remember, go for it, other than that such a diary is of no use to my opinion
