just try and enjoy the game, don't worry to much about stuff going wrong. If you anticipate that something will go wrong you'll not enjoy it as much. Keep playing it the way you are playing it now. If you ask those kind of questions here you will get mixed answers and get confused.
That said, I delete my characters when they reach the age of 10mb savefile. That's when they start getting sick from Laggittis (it's a word, look it up! best if you don't look it up)
But that's my expirience. Some people will tell you complete different stories.
Look, just PLAY THE DAMMED GAME!!!!!
