How far into the future can a reading reveal?
Typically a few weeks to about a year out. Beyond that, too many things can shift — the reading gets vague because the actual future does too.
Can the future change if I don't like the reading result?
Yes, and that's kind of the point. A reading shows what's most likely if things stay on their current track. Change the track and you change the outcome.
How often should I do a future reading?
Every two to four weeks on the same question is a safe rhythm. Checking every few days on the same topic tends to produce noise, not answers.
Which method is best for predicting the future?
Tarot and runes give you the most detail. For a straightforward question that just needs a direction, yes/no or pendulum is faster and often cleaner.
