Do keep a check, whom you give liberty to browse through your life and keep them in their limits.
Limits are important, even for ourselves (sometimes) and for people around us. It keeps you sane, for not pushing yourself harder to work and repair things that are irreparable, for exhausting yourself. Just don’t limit your aspirations and take up challenges.
Unwanted interference from people, continuous advises, are not the things you want. It is better to keep people in their limits, so they do not exceed and make your life their own.
Define your limits for people, so they would know it, through your behavior and attitude. You don’t want to be pestered by their judgments, of what you are doing in your life. It will keep problems away from you, and others will start respecting the line you have drawn for them.
