Being an entrepreneur requires a lot of different personality traits. You mentioned having lots of ideas and being creative, which is what most people associate with being an entrepreneur. What I've found is that being creative and having great ideas may be well suited if you want to be an inventor but is not necessarily the best trait for an entrepreneur as you clearly are aware from your post.

In my opinion, you need to develop thick skin to bounce back from failure and be incredibly resilient to keep pushing through when things do not go well, and trust me this happens in every business or venture. Having that type of never give up attitude combined with being able to sell yourself, your idea and your product is more important than having great ideas. Plenty of people have amazing ideas but never do anything with them or they start but give up quickly when things don't go their way.

I hope this helps.
