for me
life is like a puzzle
all those moments happening in your life are the puzzle pieces
the happy ones you'll cherish forever and the sad ones that you wished you won't face again
you might not know why but when you get all the pieces together, you;ll see the bigger picture
and I'm pretty sure you'll be proud  as hell to finish that puzzle
it's gonna be worth it
just hold on and don't let go
