Stakeholders avoid complainers like covid-19. What they value is understanding a problem and its impact. Some might want details but more importantly they are looking for solutions.
When confronted with a problem, brainstorm 2-3 possible solutions. Be prepared to present your top solution along with a brief list of pros and cons when asked.
Over time, stakeholders will become confident your ability to identify problems and suggest solutions. Your pro-active mindset will pay dividends in the future.
