Stop comparing your life to the life of others
Now more than ever our lives are being compared and contrasted to the lives of others over social media apps such as Instagram and Snapchat. This is especially destructive for someone who hasn't fully developed a proper self image of themselves. And the problem with social media is that you are never seeing the real life of someone, you are only seeing the highlights of somebody's life. The hard truth is that some people fake smile or even fake laugh in order to seem like they are happy in their picture. You can't compare your actual life to a life that is riddled falsities.
The hard truth is that you will never feel satisfied with where you are in life if you are constantly thinking about how someone is doing something better. I still use social media but I removed over 900 followers a few months ago because I just simply don't care what other people, who I don't know, are doing. I deleted snapchat because ultimately it is childish and unprofessional. Some people enjoy it and that is fine with me but I soon came to the realization last year that sending pictures of my face to someone who sends their face back is rather futile and ridiculous when you look at it in retrospect. And again I am not knocking anyone who enjoys using it, just my opinion. At the end of the day, no one should be spending more than 30 minutes a day on social media.
Back to comparison. Your life is your life and no one can dispute that, you do things to improve yourself, not to improve yourself in spite of others. So go out, be by yourself for a while, stop comparing, and start living.
