In whatever we do, there's always an uncertainty,and risks, because no one knows tomorrow. Many people are often afraid to take the risks that come with their desired perspectives.This alone can hinder advancement in one's endeavors, irrespective of the field one's in.
For anyone to make progress,one must take a bold step,and make a start,even when one's unsure at the beginning.Procrastination wouldn't be of any help as such tasks and ideas will keep piling up without any actualization and meaningful productivity.
Whatever the case,and however one's seen himself,start up in that capacity,against all odds and criticism.Remember,until you crush the lemon,you won't get to make the lemonade Take the risks,and have a firm stand.Just do it.
