ISTJs as entrepreneurs

ISTJs typically approach entrepreneurship in a calm and calculated manner. They are self-assured, honest, and extremely direct when they talk to their peers.

They put a lot of emphasis on optimizing their daily routines in order to be efficient. Productivity and organization apps like Trello can form a large part of their professional lives thanks to this innate appetite for efficiency.

They learn very quickly thanks to their ability to listen attentively when others are sharing ideas and business hacks. Their communication skills are also boosted by this trait, as they are able to respond more accurately to the wants and needs of others – simply because they listened well.

Unfortunately, ISTJs are rarely able to muster up much of a creative spark. Instead, they end up doing things by the book, which results in very bland and impersonal results. To rectify this lack of creativity, ISTJs should engage in creative writing exercises in order to further cultivate their copywriting abilities – an essential skill for any entrepreneur.

ISTJs also hate being proved wrong, as they feel that they have to be right about almost every subject. It goes without saying that such an attitude can rub coworkers and clients the wrong way. It also doesn’t help that they tend to be insensitive when disputes do eventually arise.

In order to keep these negative traits in check, ISTJs should employ a close advisor to help stifle petty disputes, act as a mediator when necessary, and to tell the ISTJ when they’re just plain wrong.

“The common question that gets asked in business is, ‘why?’ And that's a good question, but an equally valid question is, ‘why not?’”
