The bible says in the book of 2 timothy 2:15 study to show thy self approved. A work man who does not need to be ashamed, rightly dividing the word of truth.
While many limit this verse to just studying the bible, i think there is more to it.
Is there a life you dream of? is there something you want to achieve? what do you want your future to look like? Then you must put in the corresponding effort. Prepare yourself for what you want because life will surely ask you questions before it will deliver what you want to you. Life knows those are are ready and fully equipped. PREPARATION MAKES YOU BOLD ON THE DAY OF QUESTIONING.
