Embrace it~ it is the first step in truly loving
You need to develop a strong will power to be able to love unconditionally. At some point in our lives we all demand some kind of love and want to express our own love for someone. Believe in the principle of giving more and demanding less. When someone asks you for a favor always be ready to give it. Never complain that you don't have enough or you have other tasks to do. Set your priorities in such a way that everyone else comes first and your own demands come last.
When you love somebody unconditionally you want the best for that person. Think positively about them even if they make mistakes or do not return your feelings. Give them sincere advice about their future and other decisions. Always look around for the betterment of your loved ones without any envy on your part. If you have to sacrifice something of your own for them, don't hesitate to do so. Only then you will truly be able to love unconditionally.
