Let’s say you are school going kid.
Your teacher asks you “Will you take part in speech contest?”
You are bit scared about preparation and facing people, you look around for help before saying “No”
Your friend came for your rescue he takes part in it, you feel grateful. He won the contest. You convince you wouldn’t have got it .
Let’s say you are an employee now. Your manager asks you “Will you be able to complete this project before deadline ? “
You knew you can but takes just one second extra to think , but someone else commits and get that task. You seem relieved. They get good name and appreciation. You convince yourself its good, you wouldn’t have done this .
The worst thing happened here is, you missed the opportunity to prove yourself, not to anyone else, to YOU. You lost even before trying. That will be your biggest regret. Say “You can” before it’s too late ,trust me you will get half of the work finished then itself, when you say it. Don’t die with what if, do it, if not, you will atleast know your limits .
