Goal Heart

Life is a one-chance thing. It's the most worthy thing a person can do. It cannot be regretted, nor second chances are given.
Life is what it is. It's like Science that consists many branches. Emotions, such as Happiness, Sadness, Love, Hate and etc. However, love is the second most complicated to life?
Somebody told me, that to love is to discard your pride. But, for me, it's about protecting someone. How complicated is it to protect someone? Is it too difficult, to the point that no one dares to love? Or should I say that no one dares to because it happens unexpectedly?
I wonder, how can these things be complicated. If God has given us a perfect way to live. Maybe, it's just us, who make things complicated.
I can say that, life and love, these two things, can't be defined really. Because, people live different lives likewise, people love in different ways..
