How to receive HBAR?

Could you please explain in detail how I can successfully receive HBAR? I'm quite new to the cryptocurrency world and would appreciate a step-by-step guide. Could you tell me what kind of wallet or platform I should use? Are there any specific security measures I should take? Also, would it be possible to receive HBAR directly from someone else? And finally, are there any fees associated with receiving HBAR? Thank you for your assistance in this matter.
