Should I quit my engineering job to work on developing my inventions full time?

I am of course not going to share but I have 6 idea's for new products. I did a little market researched online I could not find anything exactly like them. Some are just an improvement on existing designs. I am working on my idea's very part time due to work but it seems like they have some promise. ... show more I am of course not going to share but I have 6 idea's for new products.

I am working on my idea's very part time due to work but it seems like they have some promise. If I quit I could work on them much faster rate.
