When you have got to know your decision.
You have gone through your options.
When you know which values and experiences are important to this decision.
And you are comfortable with the risks.
The time is right.
You know about the skills.

Then you are ready to decide.
When you decide you choose one option.
This is your decision.
You may want to celebrate.
Then you need to make it happen.
