Do you remember the term “limiting reagent” from high school chemistry class? When you were calculating the output of a chemical reaction, the amount of substance formed would be determined by the limiting reagent. Every chemical reaction has at least one limiting reagent. So does every group.
In every group you’re in, tell yourself, don’t be the limiting reagent.
Do not be the member of the group who determines the heights reached by the entire group. Even if that means working harder, sleeping less, adopting a more positive attitude, or stepping outside of your comfort zone in myriad ways.
In a chemical reaction, the only way to change the output is by adding more of the limiting reagent. But the good news is, a group’s potential can change just by the attitude, determination, and commitment of the members of that group.
