The simple story is, don’t do it. It never ends well and just leaves you feeling crap! Everyone is fighting their own battle so don’t assume that all is good on their side. After all, we don’t see the full picture of their lives in full detail.
Instead, we should seek the truth and should focus on comparing ourselves to where we once were and measure how we have changed since. Also, don’t compare yourself to others who are much older and wiser than you. Remember they were once in our shoes and we can learn from them.
