I take nothing for granted. Further, I do not regret my experimentation in life. I always get an inspiration from these lines from Tennyson's In Memorium:
I hold it true, whate'er befall;
I feel it, when I sorrow most;
'Tis better to have loved and lost
Than never to have loved at all.
In fact, uneasy lies the head that wears the crown, and so I will never regret the kind of life I have chosen.
