How To Be An ISTJ

1. Focus on applying judgement against gathered information

As an ISTJ, you have a gift for remembering little details and experiences from the past. However, it’s important to focus on applying your judgement against information that you have gathered, rather than against single facts or ideas coming from others. Before judging, put all new data into the context of existing facts.

2. Embrace your observant nature

ISTJs are highly observant individuals who are always looking for practical solutions. Use your observational skills to learn and understand the inner workings of things and systems. Your amazing memory allows you to make connections between present and past experiences that others would otherwise miss. Therefore, you can be among the first people to identify mistakes or problematic patterns.

3. Value loyalty and tradition

ISTJs value loyalty in themselves and others and emphasize traditions. You are highly organized and like to feel in control of your environment. Therefore, you dislike change and don’t welcome spontaneity. Embrace these traits and use them to your advantage in both your personal and professional life.

4. Take time for yourself

As an introvert, ISTJs need to spend time alone in order to organize their thoughts and ideas, and to replenish their energy. Make sure you take time for yourself to recharge your batteries and reflect on your goals and priorities.

5. Be open to new experiences

While ISTJs prefer order and structure, it’s important to be open to new experiences and ideas. Don’t be afraid to step out of your comfort zone and try something new. You may be surprised at how much you enjoy it.

6. Develop your emotional intelligence

ISTJs are known for being logical thinkers who rely on their heads more than their hearts. However, it’s important to develop your emotional intelligence and learn how to connect with others on an emotional level. This will help you build stronger relationships both personally and professionally.

7. Set goals and stick to them

ISTJs are highly focused individuals who value efficiency and effectiveness in everything they do. Set clear goals for yourself and develop a plan to achieve them. Stick to your plan and don’t let distractions or setbacks derail you from achieving your objectives.
