Computer Science : I wish my fresh year self know . You should be with team and figure out stuff problems. Know that if I want to develop Website I must study programming languages like HTML,CSS, PHP,JavaScript. If I wanna develop an Android app . I must study java plus Android from google. Dear self please be with someone who is doing what you wanna accomplish or who have same goal with you. And study more than what the teachers give and be practical with code. If you wanna do website or app, system. Do it! Study by doing it. Start by developing small projects like calculators You dont have to fully know everything to start projects as app, Websites or Digital marketing. Make sure you think about marketing also collaborate with entrepreneur marketers who have product to help you sell or reach your audience for your app, Websites . Good Luck🤞🍀🎰 ☺️
