Animal Crossing is meant to be a relaxing game. I mean its not a game for like competition or grinding. I know people get impatient when they want to get their island as best as possible and they use Time Travel to speed things up. While that can be good it can make you feel burnout quickly in a week. I found out the hard way when I was time traveling myself and I felt just so bored with the game. I didn't restart because I don't want my hard work to go to waste. So I would say take your time each day and do what you can do today. Tell yourself "you know what I can do some of this today and some tomorrow" there is no need to rush things. Once you do it day by day it will feel less stressful.
