The moment people begin to lose TRUST in you and what you do, you begin to RUST.
Irons rust after being abandoned for a while and in most cases, they never revive. The ones that will be revived will take some cleaning and oiling to bounce back to life and function adequately.
This is the same effect lack of trust in you can bring to you and your career. Your long term relevance is based on the trust those around you can build in you today. If you don’t want to become idle, irrelevant, abandoned and rusty, don’t damage the trust people have in you. In most cases, it’s hard to repair and even those who get to fix it pay a huge price in terms of time and effort to do so.
Ahead of you lies a great future, don’t damage it with dishonesty based on the extra gains you want to make today.
