I agree with this phrase because this is right , if we do today a good thing , it will turn in the future , but if we will always be like “Nah , tomorrow maybe “ probably tomorrow won’t be the time or something will change completely , so if u work hard today , tomorrow too , but if u live it on the time , and wait for someone to do it then it is not gonna happen nothing . Don’t leave for tomorrow something u can do today , cause time is time , and real work happens
