One can choose a goal to which has rocky attainability so long as they measure their progress accordingly. It is little use to beat oneself up over a goal that is consistently moving. So why choose these forms of goals to begin with? To bargain toward a silence when it comes to smaller excuses, smaller justifications as to why one can stay mediocre. Comparison is entirely complex at any age bar birth, and even then it would serve only to drain one of the momentum they have gained thus far. Moving toward action that operates with zero smaller justifications can make for far more intentional movement and far more progress in one’s discipline.
Meditate.
