To evaluate advice, ask yourself (or others who are at least as mature as you are) if it is realistic, workable and aligned with Biblical principles. It does not have to be practical, conventional or usual. Determine if the results of following the advice will be fair, make improvements and give a positive solution of direction.
Seek advice from those who are more experienced and wiser. Advice is only useful if it is consistent with God's standards; so good advice will most likely come from the most godly people you know.
