Just remember that you are going to have good and bad days - just learn to accept those days as they are. Not every day nets proffit, and some days are going to rock wild, also if you like transmogs, mounts, and all that, it is nice to take a break from farming herbs and ores, and just goof around old places.
It is going to take time to get on feet. Set yourself some reachable goals per reset (not day, a reset !) and do not burn yourself out. Treat it as a small minigame within game. The psychological part of gold making is as important as actually making it.
I am personally trying to cope with Blizzards devastating saurus news and looking at my realm, maybe are some others. Because most certainly AH has started to gain more activity - also based on statistic on journal.
Journal, by the way, is a good tool to use. Especially when you want to understand your particular realm. Like today i found on off-realm that there is an alt of mine, and theres void of certain items not seen on realm for months, and there I went to see if my game time for this month comes from realm i dont play much these days. In other words - journal offers information that can be good for decision making. But also keep in mind - about journal that ‘deals’ often are just mis listed and mis priced items and are not actually selling deals.
edit : also I remembered there was this one and its a good guide for those, who want to get some starter gold :
