If I have no record of the administrator password, is there a way to reset it?

I am on OS X Mountain Lion 10.8.5 - research online says put in disc etc... I dont have a disc, I dont even have a disc drive.


I am trying to update my OS X and it needs the administrator password to complete.  ofcoarse I should know my admin password, but I don't - when I got the new computer I had to type in so much info to set up, I forgot to keep a record of this one password... the most important and hardest to reset it seems.


Any help for a novice?  Should I go to a Mac shop?

    When selecting passwords, make sure it's one that you will NEVER forget AND no one else can figure out. 


    Old school--- > Print it out & keep in a safe place.  A place that ONLY you know about AND never forget.


    New school---> Get a password manager utility.  Highly recommend 1Password which is shareware.  Do a Google search for free password managers.
