Should I use a front-end frameworklike Bootstrap?

I am a software developer and I do not have a design-bone in my body. Everything I try to "design", looks worse than Craigslist. Bootstrap, for me, gives me just enough structure when building Version 1 of a web-application to make it look good and not paint myself into a corner. It works for me, best thing I could say is, use it on 3 projects and then make your decision
