If you have not read “Measure what matters” by the legendary John Doerr then read it today. For me the single biggest learning from it is simple – focus.
He says it out loud and very clear – “We must realize—and act on the realization—that if we try to focus on everything, we focus on nothing.” Most often entrepreneurs try to chase too many shining opportunities, all at the same time, only to realise they fell short of resources or simply their own bandwidth.
I admire InVision in this regard which has been razor focussed on their product and users. It has proven SaaS is the way to go for all imaginable type of softwares.
