Ich hatte sowohl in der Schule als auch im Studium immer ein Problem. Mangelnde Motivation. Ich hatte keine Lust mehr zu lernen und wollte stattdessen lieber zocken oder einfach etwas auf Insta oder TikTok chillen. Doch das sind miese Zeitfresser, die dich deinen Zielen und Träumen keinen Schritt näher bringen. Denn wenn du deine Ziele wirklich erreichen möchtest, kommst du nun einmal nicht darum herum, auch manchmal in den sauren Apfel zu beißen, dich auf den Arsch zu setzen und zu ackern. Wenn ich früher kein Bock hatte zu lernen, habe ich mir immer motivierende Zitate von inspirierenden Persönlichkeiten angeschaut und diese haben mich extrem angespornt, am Ball zu bleiben und für die Klausuren zu lernen. Jetzt habe ich ein abgeschlossenes Studium und verfolge meine Träume, indem ich genau die App entwickle, die ich damals so gern gehabt hätte! "It always seems impossible until it's done!"
