[Grammar] look(flash) back at/on/to

[yuriya]

Hi, everyone. When you look back to take stock of what happened in the past, I notice different prepositions follow the verb phrase "look(flash) back" as in:
look back on my life, look back at/on the year (month, vacation), look back at/on/to those days etc.

Please help me out on the proper use of these prepositions. Thanks in advance!
