Business development, management and leadership aren’t difficult because of the actual mechanics involved.  Sure, there are a lot of variables and no clear answers; but just because there is a learning curve doesn't necessarily make something hard. Consider the possibility that if you are relating to a project or endeavor as “hard” or “stressful” it just means you don’t have adequate support structures.  Business development may seem difficult, but if you had a buddy checking in with you every day to compare accomplishments, AND a monthly mastermind group to share ideas, AND a staff person handing administrative tasks, AND a mentor to give advice and make introductions, AND friends to commiserate with when things don’t go as planned, AND a coach to help you to communicate more persuasively…  it would seem a lot more manageable, maybe even fun or easy. There has been a lot of research on the impact of social support on the body’s ability to deal with stress.
