I play on a very popular realm (Burning Blade), just like many of the people before me. Herbalism and skinning are probly better money makers than mining, because they are easier to gather. I know at low levels selling Briarthorn and Swiftthistle is an easy way to get money fast, but if you are doing herbalism, this could disrupt your funds. I suggest that if you want to get more money in your 20-30s that you pick up Herbalism and Leatherworking and level them as soon as you can.
