That's why marketing consultant, writer, and speaker Brian Honigman gathered advice from entrepreneurs like Levo League's Caroline Ghosn and Buffer's Leo Widrich. They're still involved in the nitty-gritty of building successful companies, and they have plenty of wisdom to offer from persevering through hard times.
Honigman first published these lessons on the Huffington Post as "33 Entrepreneurs Share Their Biggest Lessons Learned from Failure." Marketing software company Referral Candy took the lessons and packed them into a presentation with additional context.
We've published the presentation, illustrated by Jon Tan, here with both Referral Candy's and Honigman's permission.
