I was like you for a long time. I did what worked. At bed time we would sit in the recliner and I would rock her to sleep while I watched TV and then put her in the bed. This was out of my convenience b/c it was easy and worked. But like clockwork, she would wake up in the middle of the night and not be able to put herself back to sleep. Then one day it just dawned on me, if my daughter doesn't put herself to sleep to start why would I expect her to do it when she wakes up in the middle of the night. So, I started a nightly routine, bath time, snack, lay in bed and read 2 books and then lights out and I walk out of the room. Now, yes she cried, but for the first couple of nights I would stand outside her door and do increments go back in every 1 minute, 2 minutes, 5 minutes, etc to reassure her that mommy was still there. The 1st night was hard, but she eventually went to sleep and I was right there. The 2nd night was a little easier and I'll tell ya, by day 4, she just got it. I didn't start this until 18 months, but I tell ya, next kid....definitely starting early!
