Who should I accept advices from?

As a young lad, i get a lot of advices from older people, some on the internet and some in real life. but sometimes the people that advice me are the last people I would ask for an advice from. for, religious, moral, social and many more reasons. But at the sametime I knoe I might be wrong about a lot of things because I acknowledge the idea that I'm not perfect neither does anyone. and since I interact with multiple cultures through the internet I find it hard who should I listen to. Any help?
