There will never be a completely two same person in this world, not even a perfectly identical twin will be the same, they will always be different from the very basic building block of every creature, which is from the cell level.
That is true, and with that kind of understanding, we should always believe that there will never be identical experiences that one can have. Everyone has their own story, their destiny, their own luck and adversity and so on and so forth.
so you can use that understanding whenever you feel insecure or feeling down whenever you scroll on the social media feeds, and you might think that you have been far behind from the people you know. Always remember that they have their time much sooner that you to be in that position, and what you can do, is always strive for the best, while waiting for the chance to come to you to be that person showing the achievement that you get.
In a life where social media at times can be the new standard in real social life, it is always better to check on the reality at times, so that you will not caught up in depression, and feeling less that the other you have seen in the social media.
Every human are different, maybe it is not you time yet.
