  39. 10 Steps to Success in Bioinformaticsby Webb Miller • Become a biologist. • Value your number of citations above your number of publications. • Collaborate, and do it with great collaborators. • Do not expect a warm welcome from everyone. • Be a good collaborator. • Distribute and maintain software and/or run web servers that you personally continue to use.

  40. 10 Steps to Success in Bioinformaticsby Webb Miller • Alternate between working on specific datasets and writing general-purpose software. • Write some of your own software. • Don't give up. • Be excited about your work.
