When there is deep love, you always tend to feel that you have not done enough. If you ask any mother, βHave you done a lot for your child, or all that you had to?β
She will say, βOh, I donβt think so. I feel I have not done muchβ.
In love one never thinks βI have done enoughβ.
That only happens when you get very tired and exhausted. When you have this feeling, βI have to do more (for someone)β then that is a sign of love.
