“I trust that my hard work will pay off.”

This quote is saying that what you work hard for at the end it will all be worth it. If you work hard for what you do or what you want it will all be worth it at the end because the work you did has a meaning to it. If you want something in return of what you do then you have to put effort in it. Otherwise it won’t turn out the way you want because you didn’t try. Someone who wants to work hard is going to do the work it requires. If you don’t want to work hard but you want something in return then it’s not going to go that way. In order for something to go back to you you have to work for it. For example if you want your parents to buy you a phone, you have to work for it. You have to obey what they say and respect them. If you don’t do that then you shouldn’t expect something in return. Everything has to be worked for, even if you don't want to you have to, you aren’t going to get something good in return if you don’t do anything for it.
