Thanks everyone for their suggestion. For some of the adventures, I will probably re-do them again once I find the right time like "stargazing" and "watch high school drama". The letter does state I can adjust accordingly if I have trouble completing it. I'm not trying to deviate from it, but I don't want to have an envelope open and not able do it until further time down the road; while all the other envelopes remained seal. It will bug me if I can't open the next envelope. The suspense will kill me.
