Getting Re-Motivated & Back Into the Market

I have been in the market about 10 years.  I haven't bought a property in at least 5-6.  I run another business, so I have been hiring out everything.  I only recently began really detailing my numbers and micro-managing subs, materials, cost.  I have more than likely lost my short, but built a little equity.  Although I've have time in, I lack real knowledge and creativity I have been reading about on Bigger Pockets.  I love this industry, so I'm looking for creative ways to get in, make money and continue to build. For now, looking for suggestions on creative ways to manage about 15 properties with turning over to a management company and improving efficiencies.
