Trying to de-donk myself

Reading these boards has definitely helped my play. Unfortunately I still find myself making occassional donk moves. Generally this donk behavior consists of calling raises that I shouldn't call. Losing these hands helps re-enforce how stupid it is to do so. However, sometimes I wind up winning a hand with a questionable play, and do not want to continue to make the same stupid play in the future due to positive results. Villian (UTG+1) has been just plain stupid. Raising with A rag in position. Raising with Q rag out of position. Calling huge overbets. I bought in short this game ($40), and basically doubled up off of him. So anyway, my question is how should I play this flop?. What about if the villian had a bit more skill and was more typical of 0.50/1.00?
