Building a trustful relationship with your clients.
In all professions, especially the ones including interaction with people, such as accounting, having mutual trust is the cornerstone. In order to make this happen, the first step is being patient since you need it in long-run relationships. Take you and your client as an example. Integrity is the next thing you should bear in your mind. Therefore, always try to stick to your commitments. Fallibility; don't search for excuses elsewhere! Try to be the best version of yourself. Finally, be inclusive and don't take credit for everything you do!
