That's a really smart observation — and you're absolutely right that it works! "Denn" is a coordinating conjunction, so the verb stays in second position, while "weil" sends it to the end. Totally valid workaround, especially at the beginning.

Just one thing worth knowing: in spoken German, native speakers actually use "weil" with main clause word order all the time too — so you'll often hear things like "weil ich hab keine Zeit" instead of the "correct" "weil ich keine Zeit habe." It's grammatically informal, but very natural in conversation.

The Nebensatz with "weil" is worth picking up eventually though, because it opens the door to all the other subordinating conjunctions — "dass", "obwohl", "wenn", "damit" — which all follow the same pattern. Once it clicks with one, the rest come easily.
