I have been in your shoes: At the peak in 2007 I was a full time PhD student (Physics, CS & EE), full time startup founder/exec (35 staff, acquired in 2007) and new father (child born on acquisition day - no kidding). Without really strong alignment (and great colleagues in both arenas) this would have torn me apart.

Don't set yourself up for failure from day one by shooting in all directions. If pharmacy is your passion then try to weave it into all your activities. Always remember, Web2.0 entrepreneurship accounts for 99% of online buzz but less than 30% of actual investment activity. In fact, biotech is currently the largest investment and M&A sector if memory serves from the last PWC Moneytree report. If you like coding then by all means code, but don't feel like the only possible entrepreneurial experience comes from hacking websites.

Disclaimer: I am not a biotech guy, nor am I saying that Web2.0 ventures aren't a good choice. They are just not the only choice.

At the risk of breaking some kind of HN rule, I have a bit more info on how to achieve such alignment on an old blog post: http://bit.ly/hJmCEQ
