Managing a business vs working alone (as part of my personal development program…)

Hi Brooke,
my impossible goal is starting to manifest. The next step is hiring people – and then managing them. One part is the business side and I already took your entrepreneur program. My focus now is the “human side”: I know I have some room for further knowledge/development here. So I’m a chronic people pleaser and know how challenging it will be for me to give feedback fast and well (and REALIZE that feedback is needed AND have the courage to do so vs telling myself that (problem x) will vanish by itself…). Do you have recommendations for me? Books, programs? Thank you!
