Of course, you don´t need to change. Survival isn´t compulsory.
The bad news is time flies. The good news is you are a pilot.
Sometimes it is necessary to walk the wrong path for a long time. Then you are able to come back quickly and properly.
“I don´t know the way to success, but the certain way to failure is desire to please everybody.”
Bill Cosby

“Small problems can´t be seen easily but can be rectified without difficulty. If you let them grow, they will be seen easily but it won´t be so easy to set them right.”
Nicollo Machiavelli

Experience isn´t something you meet. It is something you do with the things that have met you.

God grant me the serenity
To accept the things I cannot change;
Courage to change the things I can;
and wisdom to know the difference.
