Punctuality is a very good habit to have
Unfortunately a lot of people don't take it too seriously
Personally if i were to speak for myself..
..When i have to meet someone or be somewhere at a given time
I always try and be there at least 15 to 30 minutes early
I always like to have that extra cushion of time in my hands
I don't mind waiting
But i hate to keep someone else waiting
I always say this..
'It's better to reach early and wait..rather than reach late and suffer the consequences...if you don't value time..time will never value you.'
