First of all, its never late to achieve anything. Yes there are people you must have been hearing about who have achieved very much at 21 or 22 years of age, but every person has a different journey. Likewise you have your own journey. So don't compare yourself with other and start mending your ways. If you think that you are wasting you time in sleeping, start getting up early. Only excuses will do nothing better to you. Take hold of things and they will surely start gping right.
