Whether you choose to move on from your struggles and enjoy life or waddle in your misery, life will continue.
You can't be jealous of someone else's results. You don't know the prayer, process, sacrifice, and work they endured for it.
Make peace with your now moment. Live in this very moment and be happy with what you have. Joy enters when we stop complaining about the troubles we have and offering thanks for all the troubles we don’t have. And be aware, you have to fight through some bad days to earn the best days of your life.
Lack can greatly be the reasons for our conscious and unconscious steps in life. Mind what you lack, move for what is a must and be happy with what you have!
