As a brand-new UNIX user around 1991 and coming from MSDOS, I was used to being 'God' on my machine so I thought it would be a good idea to login always as 'root'. I couldn't understand why long-time users of UNIX knew that to be a very bad idea, and always advised against it.

Like the SunOS person, I had lots of dot-directories in /tmp. So I duplicated his actions almost perfectly.

Also like he did, I was wondering why an 'instantaneous' action was taking so long. I had to do a complete re-installation.

Ever since then, I've always logged in as a 'normal user'. My reign as 'God' in a UNIX environment lasted about 2-3 weeks in total.
