Especially in project management, there are many things that can be defined in theory. In practice, however, many things are not predictable and require individual solutions. Therefore, it is good to stick to a formal framework but always keep a certain flexibility in mind.
To be honest, the job can be very challenging sometimes, and can confront you with seemingly unsolvable obstacles. As a prospective project manager, you should definitely not be afraid of these great challenges and approach them in a simple, structured and systematic way. At the same time, a major benefit is that you never get bored, as it is super multifaceted and fascinating. Plus, it is a great role in which to learn and to advance your skills.
Above all, you always work in a team as a project manager where you only advance together and make it to the project’s finish line as team players.
There is definitely no reason for concern that this might be an issue at GDF. It is a very unique place and it is great to work in an environment where you can approach anyone at any time, regardless of hierarchical levels.
And the most important thing: Don't lose heart because of detractors or seemingly unsolvable challenges. Always keep on looking beyond the boundaries!
