Ignore what everyone else is doing
We buy a certain car because our neighbor just bought a similar one. We suddenly feel the urge to have a child because all our friends are having kids. Our coworker gets a promotion and all of the sudden, we want one. Even though we don't drink or eat sushi, everyone in our book club does, so we feel pressured to follow suit.
Unfortunately, many us fall victim to the herd mentality. We'll do almost anything not to stand apart from our fellow peers in any way. We hate the thought of being ostracized or left out, so we try to shadow their behavior -- in everything from the clothes they wear to the products they buy.
I'm of the belief that embracing your uniqueness is the key to self-fulfillment.
People will always try to impose their beliefs and attitudes on you so you can think and act like them. Why? Because it validates the decisions they've made. If you opt to go down a different path, it leads them to second-guess their own choices.
Why fall into that trap?
If you're afraid they'll leave you as a consequence of your sticking to your guns and doing what makes you happy, it says a lot about your relationship. A person who truly cares about and respects you would never do such a thing.
There's nothing wrong with looking to others for inspiration and guidance. However, it doesn't mean you have to resign yourself to doing whatever they do.
The only person you should be trying to impress is yourself. People will come and go, but you'll always have yourself in the end. If you don't want to follow the herd, don't. No relationship is worth relinquishing your individuality over. Comparing yourself to others will only leave you in a state of despondency.
Be unique, and take pride in what sets you apart from the rest. Never compromise your values or principles just to fit in. Forget what everyone else is doing and live life on your terms!
