The importance of Introspection & how it differs from meditation

[FunBun]

As a beginner of actualisation, I'm struggling to find out what to prioritise. I'm trying to build a meditation practice and that has really been meaningful so far already, but introspection is something I am not familiar with (at least not consciously).

So my questions are:

• What is introspection?
• Why introspection is helpful?
• When is introspection helpful? / Who could benefit from it?
• How do I do it the right way? (asking the right questions that focus on gaining awareness, not stress the problems further)
• How much time should I put into this? / How often should I do this?
• How is it different from meditation?
