As you become more experienced in learning how to geocache you'll find that one of the rewards is the pleasure of finding the treasure at the end. After you expended considerable energy to find the thing it's something that makes it all worth it.
... unless it's a wretched micro! Man, I hate those things.
Not only are they hard to find but it is a pain to unroll a tiny scroll and find a space on it to jot your signature in microscopic letters. There is no joy at the end, only pain. A lot of people think the same. Check out what people DON'T like about some caches here.
Unless you're going to be very creative with a micro, just don't put them out. Unless you're going to be very creative with a micro, just don't put them out.

Did I just repeat myself?
Go for quality.
If you're a creative type who can design and construct unusual containers, then my choice of container is an ammo can. These things are relatively cheap, rugged and totally weatherproof. They last for years and you rarely have to maintain them. Stuff it full of quality goodies and find a fabulous location in which to hide it.
Sometimes an ammo can is too big and obvious for the location you have chosen. This is where you get to use your imagination. There are so many creative ways to hide things that will avoid using a nano or a micro. In fact you can purchase all sorts of camouflaged containers (e.g on eBay) that you don't need to think up something yourself.
By being unique and creative you will enhance your reputation in the geocaching community and people will look forward to doing your caches. You never know, they may come and ask you for advice on how to geocache.
