@Ray Rhoads congrats on your first BP post. You can overcome your weak areas by partnering with someone who is strong in them or going to work for someone and gain knowledge from them in those areas.
@Ray Rhoads Hooray! I hope you enjoy the Managing book. It looks like you're filling up your personal library, which is always a great place to start!
There are always great book suggestions on the BiggerPockets Money Podcast, which I personally enjoy listening to! Great financial advice as well. I haven't yet listened to the BiggerPockets Real Estate Podcast, but I hear great things about it. Although obviously the great things I hear are from biased sources... but definitely worth a shot! Podcasts are great for the good ol' daily commute, and there are a ton of them available for free on iTunes.
I have a very unofficial thought on how you can learn your weak areas... unofficial in that I'm just making it up but I think it's something that's worked for me...
Instead of looking for your weak areas specifically, look for your strengths. And do that by following what really gets you pumped or excited. That's an easier feeling to follow, I think, and that will point your towards what may be your strengths. All the while, anything that makes you gag a little when you think of it or roll your eyes or gives you a sense of dread, those are probably more of your weaknesses.
It doesn't always work out that way.... for example, I'm a really good landlord (as I've found out just this year) but the thought of being a landlord makes me want to run straight into a concrete wall. But I'm good at it. But even so, it's not something I want to make a habit of. The part of it I am good at though is the project management side of it. So I can take the project management and apply it to other things.... like how I manage all of the property managers who landlord my others properties for me and I keep all of that running smoothly.
So mix your interests and strengths and follow those, and then just be aware of what may be your weaker suites.
