From my experience resilience is the most important thing that helps me to get to the objectives. Sometimes things are not easy but if you really want something keep trying, ask for help if needed and push yourself. Don’t give up easily but also don’t be too harsh on your self when things don’t go as planned, sometimes it happens and you can’t control it. If you did everything in your power to reach what you wanted to and it still didn’t happen it wasn’t meant to be.

I know it sounds super cliche but if you can find something you enjoy doing you're almost certainly going to be insentivised to do it more often and do it well. Obviously there will be times in your career where you struggle and find things difficult but if you have a goal you're determined to work towards and you can find enjoyment in your work you will succeed.
