All of Nothing Day is a day to stop overthinking or doing things halfway and either jump all in, or quit altogether.
How many people have ideas, start projects, or dream of doing something and never complete it? All or Nothing Day is a reminder of how you can't get anywhere by doing things partially or just dreaming about them.
This is a day to jump in and give your all. Really commit to something you want to do. Whether it's a business idea, a hobby, a project, a vacation, a purchase, whatever it is, stop just thinking about it of pushing it aside. It's a day to go all in or stop stressing over it and forget about it.
Just remember, this is a holiday to help motivate you, not stress you out! So pick one thing in your life and either go all in or decide it's not worth dwelling on.
