Not necessarily. If you base your validation on the opinions of others and try to please everyone then you may find yourself being pulled uncomfortably in different directions like the man who's legs were tied to separate angry horses. You could make yourself a slave to the approval of others, because there'll never be time for
you to grow.
I would ask why it is that you feel this validation is necessary. Those who attempt to judge the worth of others they've never met before are making a mistake and should be spending more time looking to their own affairs. They can try to make themselves the judge of that as much as they like, but they may as well be trying to make themselves god of all life in the universe, because that's not going to be a reality outside of their mind either. All opinions are a little biased. The best we can do is expose them to new information whenever we get the opportunity. If you tell a human that they
must grow and develop and be validated, you'll likely only befuddle them and stifle that growth. It'd be like shouting at a plant, "GROW UP, YOU LITTLE BASTARD!"
Think of all the people and all the voices out there. There are a lot, more than the mind can probably comprehend. You'll drive yourself mad trying to do listen to them all, so as you live and you meet new people, satisfy yourself with listening to their stories and remember that they're you, just from a different place and time. They feel your wants and your fears and you can share experience with one-another to help you both grow naturally. Ask yourself what it is that really makes you
you, what it is that makes you separate, and you'll have your base. You simply build on that, but don't tell yourself that you
must. It'll happen naturally, like breathing, and your mind will quiet itself.
