because not everyone has the ability to build a SaaS, I would encourage everyone to try and build something using the skills they do have and then fill in the rest later.

I started WP Extra Care (www.wpextracare.com) because I love WordPress but my skill as a developer and designer was mediocre. So I thought "I know a lot more about security for WordPress than most people, I'll offer that up." Now I've been able to add in extra skills that have been fun and also allow more of the business to run on auto-pilot. "Can you help us setup backups to AWS instead of them running on our production server?" "Yeah, I can help with that on Monday" :spends weekend learning:

TL;DR - build and launch what you can. Listen to customers and learn how to do what they will pay for. Then try learn that. You'll come out on the other side having gained both money and knowledge.
