What you give eventually comes back to you
More often than not, someone somewhere, is always struggling because of what others tell them to do. You maybe wrong, and you certainly must let others correct you when that is the case. But, changing yourself, limiting yourself because it does not suit others, is not done.
Let no one decide how you love, whom you love or when to love, even if you think you are wasting it out there, remember what you give comes back to you somehow.
You are worthy of being loved and so is the person you think isn't. Give out love ten fold even when it hurts you, because someday, in the most unexpected way, that love will come back to you, in the right moment, in the right person.
And always trust yourself, never doubt your purpose in life, never doubt your strength. You are the embodiment of the stuggles life has thrown at you, and so is everybody else. So know yourself and find your peace, and when you do, cherish it.
