"Someday everything will make perfect sense. So for now, laugh at the confusion, smile through the tears, and keep reminding yourself that everything happens for a reason." Even if someday it doesn't make perfect sense, it happened for a reason.
I think you are finally able to move forward when you can look back and accept the past, realizing there are no mistakes, no regrets just moments in life that changed you, making you a better version of yourself!
This is a very true quote, meaning that you should never give up, for the greatest thing in your life might be right around the corner. If you give in to temptation, you may never find out what success you could have had.
