Trigger Warning: Depression.
I got into a discussion today with a coworker about happiness. My argument was that, for the most part, happiness is a choice. Since I personally still deal with depression, I know first-hand what it's like to be sad without any explanation. However, making the choice recently to be happy no matter my circumstance is something that is helping me immensely. Listening to the reasons my coworker had to feel sad and/or angry felt like I was arguing with a past version of myself. It made me appreciate even more how far I've come in just a few months of deciding to look at things from a different angle.
I told my coworker that while the reasons she had for feeling frustrated and fed up were definitely valid, they didn't have to take over her mental well-being. You can dwell on little things and drive yourself crazy, or you can appreciate the position you're in for all it's worth.
Most people have the tendency to maximize the negative when, honestly, it takes a lot more energy to stress and worry about things that we a) have no control over or b) aren't really a big deal anyway. It's difficult at first to practice actively letting things go and truly living in the present, but the more you do it, the easier it gets and the better you feel.
Where ever you are in life right now, it's temporary. There's nothing wrong with being thankful and loving where you are right now, even if it's not where you want to be. I'm not advising that anyone should succumb to complacency; never give up chasing whatever it is you want in life, but enjoy the journey. You're alive and honestly that in and of itself is awesome.
Basically, instead of getting frustrated or angry over little bad things, use that energy to get excited and happy about little good things. I got excited at work today because they stocked the freezer with frozen goodies, including mini cups of Ben & Jerry's cookie dough, which I thoroughly enjoyed after my lunch. I also wanted so bad to complain about a frustrating and confusing job I worked on today, but instead I let it go. I did my job and let it go because doing anything else wouldn't have done any good.
I don't know if I got through to my coworker today; I doubt it, but making the choice to be happy can only be made by you. Keep in mind that there really is nothing stopping you from thinking positively as much as you'd like to think. And I promise, it really does make a difference in the quality of everyday life.
