Your level, other professions, and the amount of gold in your backpack would be nice information to have.
I'm going to assume that your other main profession is mining. If you want to make gold, sell your ore (or bars, depending on what they sell for) instead of using it for your crafting profession.
If you haven't already, you might want to take up fishing. Look it up in the Trade skills FAQ. It can be a lucrative and relaxing proofession.
What this means is that you don't really have to give up a fun profession that doewsn't make much gold for enchanting if you don't want to. Dropping a profession that you enjoy and have put time and effort into can be a traumatic experience. It's a different proposition altogether if you really don't enjoy engineering. Remember that the object of any game is enjoyment, not making gold.
Good idea? I really can't answer that question for you.
