The advice I would give would be to take the opposite approach and not to look at it as failed, but as not having become successful yet.

Don't give up a job and take a punt on something, do a job and work even harder on the side to build a start up. Quit your job when you are in a safe place. Don't fall for all the news about amazing start ups funded by VCs, in my opinion this is a stupid way to go about starting up your business because you are taking an enormous risk with other people's money. Do it safe and you just can not fail. Its harder but it works.

If your startup never reached success then its not failing, it just never succeeded... work towards making a successful start up instead of feeling bad that you failed.
