There are two ideas at play here: making a decision and taking action.

One of the challenges of overthinking is that you get lost in the circus inside your head — which then leads you to indecision. This is the worst place to be in. Because if you get stuck in the same place, spinning around in the carousel of your thoughts, forward movement eludes you.

What you need to do is practice making decisions and sticking with them.

Point the arrow and pull the trigger.

And do this for the smallest of decisions.

Chocolate or vanilla? 3–2–1 Choose! Order in or cook dinner> 3–2–1 Choose!

Through the practice of being decisive, you automatically become a person of action. Because action stems from a decision — and the latter comes from you.
