Strength doesn’t have to look like anger, or dominance, or even competence. Strength is persistence. Strong means that even at moments of shame and discomfort, whether it is at work or in your personal life, you are focused not on yourself, but on solving the problem. A strong person doesn’t allow himself to become part of the problem; when there is a problem, he takes himself out of the way, and does whatever it takes to resolve the issue. If you can’t solve the problem yourself, you get out of the way and ask the Divine Higher Power and other people for help. You maintain your composure, and keep going.
Discipline isn’t necessarily taking on new regimens and drastic self-improvement plans. It is staying in the trenches when you are under fire. A soldier does not say, “Hey! I’m done with this! I’m outta here!” If he did that, he could get shot by enemy fire right away. Do you know who your enemy is? It’s your ego. It’s letting negative feelings take over and suck the life out of you. Do not give up. The only way out is through.
