Whatever it needs to look like i want it to.  That could mean anything and really depends on the photo or "look" i am going for...

I used to post images with no postwork, thinking it was a good idea for my photography, but then i realised that digital images need postwork to bring them to some sort of level of "goodness"... i then went overboard and did a lot of postwork and discovered a lot of things i didnt previously know about Photoshop and now i just sit here with that knowledge and apply it where i see fit.  How i see that as beneficial is that i can now look at a scene and picture what i can get out of it with postwork should i want to (one example of that is people... "oh i can take out that person walking in my shot when he steps infront of that wall" - click).  So if you really only resize and levels adjust your photos i would recommend having a severe play around with the full force of photoshop on some of your shots then you will just learn what is there so you can apply it when you think it is applicable... and there are a lot of processes etc out there!
