If you actively engage in introspection and personal development, you already have a lot of wisdom and experience you can draw from when you come across a challenge or a struggle. Often, it's not that you need to learn something new.
Rather, you need to remember how much you already know and utilize what you already have.
How to do it:
Create a list of insights, tools, and resources that you can lean on when you need guidance, advice, or a reminder. You can create a list in a notes tab or have a journal and keep compiling new tools.
