Develop your problem-solving skills

Differentiate problems from challenges.
For example, interviewing 10 people across different continents within 2 months is challenging but doable. However, lacking the funds to travel and meet these people could be a problem.

Keep trying, don’t make excuses.
Excuses can prevent you from trying at all. For example, don’t use excuses that run along the lines of how you’re not good enough.

Focus only on the problems you can handle.
If you can’t do anything about your problem, then it’s not really your problem to solve, so move on.
