Working through the process:
What do I want for me and what change(s) would it take to achieve it? What would be the consequences? Is it worth the risk?
Overwhelmed with what it'll take to do what would need to be done?
Halt. Don't go 'out there' feeding the fears in an imaginary scenario...stay in the moment and climb that potential ladder one step at a time. If in the end it does not work out as we had envisioned? Well, at least we tried, and now we know. If it does work out? Well,, well, well, how about that? We did it.
Bottom line: Think it through. Balance the heart and the head.
Still want it? What's the loss in trying? Go for it.
