Comparing our lives with other people's lives is unfair, to them & to us. It's unfair to them because if we become jealous of what they have, what they know, how they look, etc., we start to resent them. Then we can no longer appreciate them as the wonderful person God made them to be.
It's unfair to us because it limits God's plan for our lives. Comparison says to God, "I want to limit Your work in my life to this & nothing else. I just want to be like this other person."
But God has an individual plan for each of us. His plan for you is greater than you could possibly imagine. Stop looking at His plans for others so you can walk in the plans He has for you & receive the blessings they bring.
I'd like to mention that MANY of us have probably done this before. It's a BAD habit that must be broken quick! Let's not settle for what we want. God has bigger plans for us ALL. Don't fall into what others are doing, what they have, where their going etc... Lets remember, we need to stay in our own lane, stay focus & be prepared when our blessings arrive.
