Not to be a downer, but one perspective is that there is no meaning to be found and any purpose is yours to define. Both Stoic and Absurdist thinkers have written from this angle. I'm not an expert, but realizing there have been smart folks dealing with the same issue since ...forever, has helped me power through. Exercise is a good choice, spending time with my dog and experiencing life through their eyes, being out in nature and connecting with the geology and biology, the physics and chemistry of existence fills some gap for me. YMMV
