When you have no guaranteed path to achieving your goals, think about if the gains outweigh the losses and if it's there is a good enough possibility to achieve your goal.
If you get to the conclusion that the risk is one worth taking, make a step by step plan on how you're going to execute this project and what you're going to do if anything goes wrong.
Make sure that everything you need to start is ready and prepare a plan B and C, just in case.
You have the option to wait another 6 months and start then, or to have 6 months worth of experience at that point.
Which one sounds better?
You've probably been planning this for years and you know that all you're doing now is putting it off.
But if you do need more information, it's about time you acquired it and started to properly plan the whole thing.
Your first, second and third step, starting point, the main goal and every smallest little detail in between.
And now that there's almost no chance in the world that you're gonna fall so hard you won't be able to get back up, throw yourself into this adventure and good luck.
