Music. Unless you're not into that. Comedy? Stand up comics???
I know! Chug two bottles of robotussin with nothing but DXM in it, smoke some weed and listen to stand up comedy and meditate to diverse styles of music. I like to meditate to turntable scratches.
To get the more powerful emotions rolling in like love, joy, anger, sadness, etc., I would suggest looking into artistic ventures and learning to see the beauty in life, everything that is awesome and beautiful about human beings, even as we are covered in all the mud, blood sweat and tears. Read some classic novels and poems, try different styles of music, and explore the full potential of your headspace in all the beautiful things it is capable of conjuring mentally and physically in all it's multifaceted forms and keeping the self fully unified.
I think this happens because of a lack of not asserting your will into new mental frameworks you're not used to because you identify with a certain personality complex which maintains a thought structure anchoring the perception into an expected vantage point.
For example, when I watch a sad movie, my initial reaction is to trash it, degrade it, joke about it, and just be a troll even if the movie I'm watching is actually a good movie. It's easy to be a troll with anything. But I've learned to use my will and force myself into taking the movie seriously and emotionally engaging myself into it's plot, as opposed to CHOOSING to be an heartless sociopath.
It takes a little bit of work but it's not too hard to cultivate some emotions in balance with intellect. Just try new things and try to seek what you find to be beautiful and manifest into physical reality
People tend to forget that Magic is an art first and foremost.
Of course, keep the intellect sharp as well.
