Your actions are determined by your values. Every family hands down its values from one generation to another. In that sense, the values handed over to you, by your parents/guardians or whoever raised you, will have a say whether you succeed or fail. Your upbringing and your family has had tremendous influence on you so far, whether you like it or not.
Good families handover wholesome values that will go a long way in helping its family members to succeed in life.
No matter how good a family you belong to, you will have, definitely, missing strands of values as no family is perfect. Moreover, along with the wholesome values you would have also got the disfunctional ones.
Over and above this, you would have changed your values, mostly unconsciously, living your life so far and hopefully you have changed the dysfunctional values.
Rarely do people examine the values they have inherited. It is a very important activity.
Examine your values and begin to cultivate the wholesome values that are missing. You need to do this not only for yourself but also for your children and rest of the generations to come.
Generations down the line, they will thank you for it.
