A Balanced Approach.
Support can come in many forms. It can be very intimate and personal, or it can be sporadic and acquaintance like. Both of these forms of support are important to maintain a healthy lifestyle.
Your close friends and family play an important role. They can either be saboteurs, or cheerleaders. Knowing how to mentally tackle each is the key to staying on your game. Self efficacy, your own capacity to produce a desired effect or result, is probably the most important relationship to nurture. Knowing how to produce results on your own can make the saboteurs silent, and the cheerleaders a pleasant side effect.
