Maybe I'm just growing up, or building "character", but I realize I will always have to endure bullshit in life that I have no control over. In college, it's going through unhelpful TA's and price gouging by Pearson/Housing/etc. At work, it's maybe office politics or even in consulting it's unreasonable clients. A friend would tell me to "suck it up and drive on".
I'm slowly cutting out unessential social media. I only check the news twice a day. I've listened to "this is water" by David Foster Wallace. I've read the Cracked article on Six Harsh Truths. I do exercise/yoga and slowly am integrating ten minutes of mindfulness into my moring. I'm still crabby.
But there are some things that are resistant to cynicism, like having meaningful friendships and relationships. Or working diligently to achieve some big dream of yours. Or getting out of the corporate world and walking the entrepreneur path.
For as much as bullshit exists in the world, there are also genuine things to pay attention to and care about.
If you feel you are cynical all the time, then that means you haven't found something that you can genuinely devote your energy into.
