If I could travel five years back, I would tell myself to take more risks and learn how to market. I would tell myself to not become a slave to the dollar bills, because if I did, I wouldn't be able to chase my dreams. I would tell myself to always be a doer, to go out and try new things instead of being stuck in a dead end job. I would tell myself to go after my dreams and make them a reality, because that's what life is about.
Stay calm, what you're getting mad about probably isn't worth the stress or blow-back. I would often get mad about things at our startup and it really wasn't worth it.
Nothing really as far as career goes. If I say anything, I will loose the good parts of the journey too. But, if I could meet my self when I was 20 I would advise them more on matters of love and family.
I'm 19 currently so 5 years ago Internet was just a beginning in my country.. so one thing i would definitely advice my younger self is stop following what everyone else are doing like gamjng, binge watching, literally doing everything nonsense and focus on what I should have actually done. Which is "START A SIDE HUSTLE :)"
