It's no use wanting to waste your time trying to change someone you don't want, the priority must be yours. It's normal to have many people who will accompany us throughout our life, but when you get into changing a person, actually who changes is yourself.
Even if you try to change someone, you may notice that you end up absorbing what you yourself said so much to the other and you learn and awaken yourself. Sometimes we are the ones who need to change because we are already going downhill.
Try to align your life with those who are open-minded and positive in life to achieve the ideals of life. You've already noticed that it's hard to influence people, but it's easy to be influenced by them, even worse if you're negatively influenced.
It's time to think and reflect that it's time for change to happen in ourselves and not in others, after all, our life depends on ourselves, and not on others.
Your dreams are yours, your life is yours.
