Leaving Corporate Job

So what other tips or suggestions do you have for someone who's deciding
to leave their corporate job?

I would say make sure you really know what you want to do. Make sure that this is the right path for you. Talk to people, get advice, seek advice, talk to the coach, talk to somebody else, a friend of yours, who might have ventured into entrepreneurship. There's so much that I didn't know before I went out on my own, but I just knew that I needed to. There's a lot of, what's the expression? You don't know what you don't know. And learn them along the way. Join networking groups and meet people. People love to give advice.
People love to share the tips that they've experienced. Nobody needs to recreate the wheel. Network and share and brainstorm and mastermind.
If it's really something that you want to do, then go for it. And like I said before, bet on yourself. You're your own best bet.
