You can choose not to join every fight you're asked to be part of - that's the idea in this quote. Just like getting an invitation to a party, you also get invited to disagreements. But it's okay to decline. Not every argument needs your attention. Imagine if you had a lot of invitations – you wouldn't go to all of them. Similarly, you can choose which arguments are worth your time and energy.
Think about your day; you have many things to do. Arguments can be like detours, taking you away from your goals. If you attend every argument, you might not get to do what's important. It's like saying no to a side road so you can stay on the main path. This quote reminds us that it's wise to save our energy for things that truly matter.
Sometimes people want you to argue just for the sake of it. It's like a game where no one wins. But you don't have to play that game. You can decide to stay out of it. You have the power to choose where to spend your time and effort. This quote encourages us to be selective and not feel pressured to engage in every argument that comes our way.
