You'll never create the perfect business plan, never find the perfect partners, the perfect market, the perfect location, but you can find the perfect time to start.
That time is now.
Talent, experience, and connections are important, but put your all into enough new things and some will work. Take enough shots, and over time you'll grow more skilled, more experienced, and more connected. And that will mean a greater percentage of your efforts will succeed. Take enough shots, learn from what didn't work, and in time, you'll have all the skills, experience, and connections you need.
