When i played with friend each one of us had a ideia of how to play the game and is basically was: "I'm doing what i tried and enjoyed"
Personally i don't like fishing in Stardew but a lot of people actually love this feature.
Also, you don't really need to feel this way about the game, it's not like you're competing with someone, just take you time fiding what you like about it. Later in game you can use sprinklers with a area of 24 blocks and there's a lot of little things like this that will help you overtime if you still feel stressed with dailly tasks.
