purposefully risk giving yourself a bad trip by thinking about the worst aspects of yourself that you hate the most. If scared of a bad trip don't do this, but if you're willing to risk it, it can be the most useful in this way. You can answer why these aspects are how they are easily in that state, and this can make powerful change in your life. If this causes the trip to go sour, don't worry, thats part of the plan. Having your worst qualities laid out in front of you with no sugar-coating can be a bit painful, but because its a bad trip in terms of not having fun, doesn't mean its a bad trip for you. Still a good trip in the end, just not fun to go through.

Try drawing your visuals as they appear
