People who accomplish great things in life have a capacity that simple things like love, family, etc cannot fill. Have you ever watched "A beautiful mind'? If you did, you would understand where I am coming from.
We often set sail upon a certain route in our lives. At times, we may derail from what was set to be accomplished. When we do, something or someone comes into our way to remind us to get back on it. But have you ever questioned what veered you off the track? Was it love? Or was it your indecisiveness?
Do not be too certain about what can complete you as a person. It is not always the "big" things that you aspire to accomplish in life. Love can fill the desire in you so much that you are willing to sacrifice the "big" things. Or could it be that love can fuel you to accomplish even bigger things?
And so, which party do you seek allegiance to?
