You don't know your journey either.One day you could be rich and tomorrow you could be poor.You should live your life because you've only got one so make as many memories as you can,because one day you will regret the fact that you didn't take that risk.People criticize others because they don't know what to do with theirs.Just because you don't know the ending of the story yet,that doesn't mean that you should stop reading the book.
