I'm a newb, I started yesterday and found 4 local micros on my first day, and a further 1 today on my lunch break.
Before reading this thread, I was about to make the common mistake of rushing to do my first hide.
After reading all the comments on this thread, I've realised that I don't yet have the experience to tell the difference between a good and a bad cache. All the finds seemed good to me so far because of the initial excitement of starting this new hobby and making finds.
I will now wait until I find 50ish before considering hiding one of my own. by that time I'll know whether Geocaching is something I'll stick with in the long term and I'll know what makes the difference between a satisfying find and a "Meh" find.
In the meantime, I'll continue reading the forums for more good advice.
