Promise never become a permanent one because the successful promises are rare in this world. You may hear so many promises but we get very rare truth ones.
Never expect promise to be thruth. Because only the trusted ones can handle the truth. The temporary sets of these feelings can’t handle the truth.
Before expecting something like that first trust yourself and make fulfill your dreams and point out the truth.
Make sure of your feelings and then promise to someone. Promise has so much of value in the pure world. Don’t make the promise to feel shy.
