There is nothing wrong with failing at a few things in life. We all have been there. At certain points, you make whatever that is you are doing and then there are other things which cannot be accomplished by you, irrespective of how hard you’re trying not to be a failure.
It hurts to realize for a fact you aren’t good at something. It hurts real bad. However, the good news is these people are probably worse than you. With every sort of planning, they somehow manage to wreck things for themselves.
