First — if you are in love — that’s a good thing — that’s about the best thing that can happen to anyone. Don’t let anyone make it small or light to you.
Second — There are several kinds of love. One is a selfish, mean, grasping, egotistical thing which uses love for self-importance. This is the ugly and crippling kind. The other is an outpouring of everything good in you — of kindness and consideration and respect — not only the social respect of manners but the greater respect which is recognition of another person as unique and valuable. The first kind can make you sick and small and weak but the second can release in you strength, and courage and goodness and even wisdom you didn’t know you had.
The object of love is the best and most beautiful. Try to live up to it.
If you love someone — there is no possible harm in saying so — only you must remember that some people are very shy and sometimes the saying must take that shyness into consideration.
Girls have a way of knowing or feeling what you feel, but they usually like to hear it also.
It sometimes happens that what you feel is not returned for one reason or another — but that does not make your feeling less valuable and good.
If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal.If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. For we know in part and we prophesy in part, but when completeness comes, what is in part disappears. When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me. For now we see only a reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known.
And now these three remain: faith, hope and love. But the greatest of these is love.
