As a man, you need to understand;
1. A man without money has no voice. Fix your finances before you try to fix the world.
2. Once you go through your worst time alone, you really don’t care who stays in your life anymore.
3. People respect you more if you are in great physical shape.
4. Have a clean haircut twice a month. Dress well on every occasion. Smell nice. Talk slow. Smile when necessary. Everyone you meet will respect you.
5. Be private, accept the loneliness, and fix your life. No one is coming to save you. Your life is 100% your responsibility.
And that's maturity.
