I agree with both previous posters actually, in addition to WBTB. The combination of this three: being present and aware throughout the day, WBTB, and SSILD has worked very well for me. (I don't quite do ADA awareness, but more of an all day mindfulness - at least I try to!).
I also really like Sageous's Reverse Reality checks for building self-awareness.
I personally use meditation and mantras as well, but this may be a bit more time consuming.
