24 – I wish

I wish I knew what I know now when I was twenty
I wish I had the physique I had when I was twenty

I wish I hesitated more before speaking unkindly
I wish I hesitated less before speaking kindly

I wish I had laughed more often at life
I wish I had cried more often at life

I wish I were more spontaneous, but
I wish I were more organized

I wish I could rewrite the past where I failed
I wish I would live fully in the present
