My passion, team spirit, and leadership abilities,and sound physical training enabled me to lead the University Cricket team.
Yes, take out that extra "and."
After this sentence, it is better if you add a thesis statement that tells the reader what you want her to remember after she finishes the essay. What if you change the order, like this:
Since my childhood, I have been fortunate enough to have experienced many successes. I was provided with the circumstances that made it possible for me to keep single-minded focus, and I excelled in whatever I set my eyes on. My passion, team spirit, and leadership abilities and sound physical training enabled me to lead the University Cricket team win many national level tournaments. My interest in science made me work hard to pursue engineering at IIT.
Now the para ends with a sentence that you want the reader to remember. You could add one more detail to that sentence:
My interest in science made me work hard to pursue (what kind of?) engineering at IIT, because I believe that engineering is ___________ (how is it significant? Art? Innovation?)
The last sentence of the first para is important!
Make this all one paragraph:
Early on in my career, I started connecting ...spanning across industries as Insurance, Healthcare, Banking, Auto, Industrial, and Media.
