Why is there a photo of SpaceX Falcon Heavy rocket launch above?

Since my childhood, I have been fascinated by our universe, space exploration and science fiction. It was an incredible feat to land the two side boosters back on the Earth after pushing the rocket towards outer space. While watching this footage, I realized that this was symbolic of my life motto, a quote by Theodore Roosevelt - "Keep your eyes on the stars and your feet on the ground". Awesome, right?

It reminds me to dream big, be creative but at the same time live in the present and be humble.

Testimonials

"Nissim was superb to work with - always proactive and highly responsive. His knowledge of SQL, relational databases, SQL Server, and both 3NF and dimensional modeling was great, and he was both personable and approachable. His experiences at Holland America Line and IBM definitely increased his effectiveness in working with students learning database administration and development, and his work ethic and communication skills were definitely of the quality I would expect. I would look forward to working with him again."
