Well , word by word it's: I find a road or build my own".
1st: I'll use future in the first sentence; I'll find a road or build my own."
2nd: I wonder if there isn't an implicite meaning hidden, something like: "I'll find my way......., but don't know how to finish .
Perhaps I'm just looking too far.
Hope I helped you and didn't confuse you.
One thing is sure you can always use the 1st solution.
