There are many ways to build trust within an organization or team, where people work highly satisfied and engaged. One of them is helping each other.
We feel happiness and satisfaction if we can help others or make positive changes in their life. As we can help others and make them happy, the same way others can help us and makes us happy too.

And there are for sure many opportunities to get supported (otherwise you do not need a team).
Ask genuinely for help, if you want to see how the trust is emerging within your team.

Another positive side effect will be that you get more self-confident since you are showing vulnerability.
The best way to connect is DIRECT connection without the colors of EGO.
Connection through help bonds a team and creates trust.

Good leaders have good teams; great leaders have great teams.
