What you decide to believe is what #psychologically becomes #true, even if it doesn't align with #reality. It therefore behooves you to develop a radical acceptance of reality, then take your cues from it in terms of the beliefs you #inculcate. Then you will have inbuilt evidence to reinforce your belief system that are also true, enabling you to resist many kinds of #deceptions.
That path will save you from a lot of wasted time, enable you to get what you want faster, save you from losing who and what you've obtained, and make you more skilled in stewardship.
