“The secret of getting ahead is getting started.”
– Mark Twain –
The best time to make a change was yesterday. The second best would be RIGHT NOW!
Do not wait for the elusive “better timing”. There will always be something standing in your way. There will always be something not perfect. There will always be something missing.
Get started anyway!
Figure stuff out while you go.
You cannot figure everything out ahead of time, because you'll never know what is coming. Stop trying. There is no total safety.
You can never fully prepare. If you chose to worry today for what might happen tomorrow, you will be worrying about the wrong things – and wasting a lot of energy doing so. And time. You might get the energy back, but you'll never get the time back.
Look at the worst case scenario. Decide how bad this really would be (because often it is not life-or-death). Decide if there is a simple way to avoid the “worst case”, if it makes you feel better. Then get started on your journey.
What are you waiting for?
