ISFP vs ESTP
Here’s how you can connect with your friend better:
Speak up intentionally
Make it a point to make your feelings and thoughts heard, no matter how inadequate you think they may be.
Use objective logic with your friend; avoid using emotion or personal values to convince him/her.
Don’t take it personally
Your friend may say things in jest that appear offensive or insensitive to you; best is to not take it personally and realize it has more to do with the issue.
Stand by your ideas with reason
Your friend will challenge your ideas; stand by them with reason but don’t expect your friend to accept it. He/she enjoys a challenge.
Be open to changes
Your friend is likely to make changes to their plans spontaneously; don’t be surprised and be patient with him/her.
