None of us are the same. We are all different in many ways. And we can never be the same. Even siblings growing up under one roof doesn't grow up and have the same exact life as their siblings. Humans are different inside and out.
Comparing yourself and your life with others is a waste of time. It can never be a good comparison. The backgrounds, the personalities, the preferences are all different. As Dr.Wayne Dyer says, "Be better than you used to be. Don't try to be better than others". Stop comparing yourself with others. You can never make a perfect comparison. But compare yourself with what you used to be.
What happens in the life of others does not affects you unless you allows it. Let them be as who they are and lead their own life as they want it to be. Let it be and let it go.
Instead, put the focus on yourself. Cultivate the good habits in you, fading the bad habits. Help others by helping yourself. Be inspired and inspires others. Love yourself, care for yourself and the goodness will just spread by itself. Be grateful with what you have and turn to your inner self for guidance from God.
The most important thing is that whatever you do, be sincere. Be true to yourself. Don't try to be someone else. You are you. Nobody can change it. Just be the best you.
Love yourself, and create a beautiful life to live here in this world and in the hereafter.
