What is self-determination? Basically, it means that it’s better to paddles one’s own canoe, than to wait around to be invited onto somebody else’s yacht.
The downside is, of course, having to travel on your own steam. There’s no conveyor belt, there’s no rocket engine. There’s just you, and “just you” takes forever.
But you knew this already. The only issue is whether or not you have the temperament and stamina for it.
