If you're careful, decryption should not just be a matter of cycles.
It should only be possible:

 - if the key is guessable.  If the key is short enough then
   decryption is indeed just a matter of cycles.  So use a long key.

 - if the encryption algorithm has a weakness.  This may be discovered
   at any time.  A short key by design (e.g. DES) qualifies as a
   weakness.

 - circa 2015 (or whenever quantum computers come online) if you use a
   public key cryptosystem.  So use single-key encryption for your
   personal journal.
