Don't change yourself for someone who might later on leave you
It's better to be yourself
To be honest to yourself about what you really want
And most importantly love yourself first before loving anyone else
If a person truly loves you, they'll love you for who you are
And not for what you are trying to become
They'll never try to change you into someone you're not
But instead they'll admire you
They'll try to bring out the best in you

Never think that changing yourself will make you happy, will make you a better person and it'll make that person you are trying to change for happy
But instead confidence and hard work will make you a better person
Maybe it might make you happy but...
