Be patient with yourself

Because of their strong work ethic, ISTJs may blame themselves if things don't go according to their established plan. You can experience more success by having patience with yourself. Practice this concept by focusing on progress rather than perfection, prioritizing one task at a time and stating kind affirmations to yourself.

Accept help from others

Even though ISTJs are introverted individuals, they can benefit from accepting help from others. Instead of trying to accomplish tasks on your own, be willing to seek guidance from individuals with more experience.

Create time for leisure

While ISTJs are goal-oriented, it can be beneficial to their productivity if they take regular breaks. You can create time for leisure by only completing work-related tasks during scheduled hours and engaging in hobbies and relaxation during your time away from work.

Question standard work processes

ISTJs respect established authority figures and work processes, but they may become overly loyal to standard operations. If you notice errors or inefficiencies within existing processes, you can develop a habit of questioning these elements respectfully instead of adhering to them without doubting them.
