Networking and meet new people : IS IT WORTH IT please ? I will not promote

I WILL NOT PROMOTE **How much have the people you've met helped you to succeed?** I'm thinking about whether I shouldn't try to force myself to meet as many people as possible in order to get a trigger, a business idea, partners, or whatever. Because when you are a stranger, people don't take you seriously or don't want to work with you, try ideas etc. **I'd like honest opinions please.** I know there are solo founders but didn't they have friends etc. to help them test the MVP, invest money, accompany them ? Maybe I am delusional and I am distracting myself with bullshit excuses. Did you really do everything on your own?
