Easily Raise Shelly's Heart Level
Every time you speak to Shelly and request a rucksack upgrade, Shelly gains heart points - even if you don't have the items to create the upgrade. To easily get Shelly to 10 hearts, request the rucksack upgrade over and over when you don't have the necessary materials with you. This is useful because the amount of money you make working part-time at the Tailor Shop is based solely on Shelly's heart level; therefore, if you raise her heart level this way, you can easily make a lot more money in your part-time Tailor Shop work.

Increase Villagers' Affection Fast
Every day you can increase villagers' affection by 10% of a heart by giving them gifts until they no longer accept them. Giving them unliked gifts lowers their affection, but you are then allowed to give them extra gifts to make up for that lost affection. There is no limit to the number of unliked gifts you can give per day, and once you decrease their affection to zero it won't go any lower. However, you can continue to give them unliked gifts, which will still increase the number of favored gifts you can give. This effectively allows you to give an unlimited number of favored gifts, bypassing the 10% cap.
