Manage your own career, if you don't enjoy the work and management doesn't listen to your requests find something else. I ended up getting stuck for years doing work I didn't like because I didn't have the confidence to manage my own career
Well, I guess I would advise myself to not be afraid… not be afraid to ask questions (even though they might look silly at the first glance), make mistakes and change things if you are not satisfied with them.
Don't get too comfortable with your job and workplace. Especially at the start of your career. If you don't see an opportunity to grow, find a better job and switch asap.
Focus on building the right processes – for everything in life. Such a simple thing as eating well can make a world of difference for your performance and life quality.
I would tell myself, don't be afraid!
Travel, meet, take risks, speak.
You are young but the world is not going to end because of a mistake, fall and get up, not everything should be perfect, not everyone should like you, be what you want to be.
Time passes and there is only one life, one opportunity. Lives! 💪🏻
