Just take the first step.
Don’t get bogged down in worry about how it will all play out. You can’t know the exact details anyway.
You do need to take action, though.
You can’t just think about what you want to do. You need to do something about it.
So, get started.
Just take the first step to get going, and then take the next logical step, and so on.
They don’t have to be huge strides. You can start small.
