So first off, being late for your project definitely does not set a good example for everyone in the class. You're making yourself look bad in front of everyone, because it's like showing them that you procrastinate and all that, so it definitely does not make you look good. And I am not trying to bring people down, I'm just saying my opinion. If you are on time, it obviously would make you feel good and happy about yourself! But if you were late, you would probably be sad, and wished you'd done better on keeping on time.
Trust me on this guys. I've learned from my mistakes that doing something late just brings down your happiness level for a while, and you regret doing it. For instance, I turned in my script late before and it was horrible! Instead of the A I deserved, my grade was dropped to a B, and it completely ruined my straight A's for the whole school year!!! Just ONE B!!! And it was all ruined...All of it...it destroyed my goal of getting straight A's for the whole year! If I had turned it in earlier, I would've gotten that A... So you can see how that made me feel about myself for a while... I was so upset.
In the future, if you turned in something late, or was late to something, it would probably be more serious than it would be now. As you get older, I believe things get harder, and you have to work more for things to be right. If you were to go to an interview for a job, and you lost track of time, so you were late, they would not appreciate it. Since you are older, they expect more from you, now that you know more things and you know how to take responsibility of your own things. So, the person you are being interviewed by probably would be unsure if they can trust you with tasks and deadlines due to being late for your interview.
The main thing is that you do things when it's supposed to be done, and no later so that you can set a good impression on the person you're working with or for. As time goes by, things become more serious, so time is very important to work with. Don't procrastinate and think you have all the time in the world, because sooner or later, your deadline will come, and it won't be easy. Being late would set this feeling over you, and it won't be a very good feeling, so just keep in mind that being on time is worth it, even if you have a lot to do to get to it. And trust me, you'll know what I mean. It may not be very easy, but try your best, and it's ok if you make mistakes, as long as you learn from them. With that being said, let me post this blog so I'm not late!
