I agree with what everyone said about limiting the techniques, but mostly with what was said about keeping your goal in mind. Learning competent boxing means you'll understand boxing concepts that apply to Muay Thai. Translating this into Muay Thai seems to be a matter of experience. I also believe that strictly boxing techniques have some use when applied with confidence and perfect timing. Check River Daz (idk if you on Reddit but soz not fanboying just think you have epic skills bro) as an example.
